Neuere Methoden der Praparativen Brganischen Chemie. (New
methods of preparative organic chemistry). Edited by W.
Foerst. Verlag Chemie, Weinheim/Bergstr., Vol. IV. 1066.

1967, viii, 280 pp., numerous figures and tables, bound
D M 38.-.
After the appearance of the first volume in 1944, “Neuere
Methoden” made its mark within a short time, and was used,
not only as a convenient and very useful source of information to the chemist engaged in preparative work, but also by
advanced students preparing for examinations. This tradition
was carried on in 1960 by the second and third volumes [I], and
the present review deals with Volumes IV and V. Like the
earlier volumes, they contain a selection of articles from
recent volumes of Angewandte Chemie, and deal exclusively
with important and recent methods of preparative organic
Volume 1V : cc-Additions to isonitriles, triple additions, and
four- component condensations ( I . Ugi 1962 [ZJ, revised 1965);
the text has been rearranged, the nomenclature has been
partly improved, and
nsiderable supplementary material
has been added in places. Isonitrile syntheses ( I . Ugi et al.
1965, revised 1965). Reactions of sodium hydrazide with
organic compounds (Th. Kaufmann et al. 1964, revised 1965);
a number of new findings and numerous procedures have
been added. Ethynation reactions ( W. Ried 1964, revised
1965); Parts I and I1 have been combined, and supplementary material has been added in places. Syntheses with nascent quinones ( H . W . Wanzlick 1964), cyclization of dialdehydes with nitromethane (F. W . Lichtenthaler 1964, revised
1965). Use of complex boron hydrides and of diborane in
organic chemistry ( E . Schenker 1961, revised 1965). This
article has been completely rearranged, and now contains
1700 references instead of 865 and 49 procedures instead
of 22. This contribution is a most valuable review of this
extremely important and rapidly developing method.
Volume V: New reactions of alkylidenephosphoranes and
their preparative uses (H. J . Bestmann 1965); the three parts,
which were originally published separately, have been combined. Syntheses with heterocyclic amides (azolides) ( H . A .
Staab and W . Rohr 1962, revised 1966); many results from
recent years and 11 procedures have been added. Organic
syntheses with imides of sulfur dioxide ( G . Kresze and W.
Wucherpfenning 1967). Syntheses of naturally occurring fatty
acids by sterically controlled olefination of carbonyl compounds ( L . D . Bergelson and M. M . Schemjakin 1964, revised
1965). Syntheses with s-triazine (Ch. Grundmann 1963, revised
1965). Silylation as an aid in organic synthesis (L. Birkhofer
and A . Ritter 1965, revised 1965). Organosodium and organopotassium compounds ( M . Schlosser 1964, revised 1965); Parts
I and 11 have been modified and combined, and some of the
procedures have been revised.
All thecontributions now containvery usefulprocedures, either
in the body of the text or at the end, which may be used
directly. Each volume again contains a n index of reactions
and compounds. The articles are very readable, since they
are clear and not too long. The authors have spared no effort
to present their own fields in a convenient form. The formulas
and the presentation are very good, and printing errors are
rare (e.g. IV, p. 172). The printed area of Angewandte Chemie
has been halved horizontally. Those who regret that this
again makes the books wider than they are high (21 x 18.5cm),
so that they spoil the appearance of the row of books on the
shelf, can console themselves with the modest price that can
be achieved in this way.
Many may think that an important preparative method would
be better described in a detailed monograph or handbook.
However, there are many points in favor of the publication
and continuation of this series. These are not subjects
that can already be found in specialized books, but new

developments, which ought to be made known as soon as
possible. In this way, many interesting points can be presented for which a complete and final description is not as
yet worth while.
Readers of Angewandte Chemie may think that they have no
need for these volumes, but a given preparation will be easier
to find in Neuere Mcthoden than in Angewandte Chemie,
and in addition will contain more recent information.
Another advantage is the collection of unrelated topics. The
study of these volumes must be recommended to every
chemist and postgraduate student. They provide a broad
view of progress in preparative organic chemistry, and are also
excellently suited for revision by subscribers to Angewandte

Mikromethoden fur das klinisch-chemische und biochemisehe
Laboratorium (Micromethods for the Clinical Chemistry
and Biochemistry Laboratory). By H . Mattenheimer. Verlag Walter de Gruyter & Co., Berlin 1966. 2nd Edit., x,
223 pp., 35 figures, plastic cover D M 30.
The publication of a second revised and enarged edition of
“Mikromethoden” is very welcome. The micromethods,
developed more than 30 years ago by K . Linderstrctm-Lnng
and H . Holten, are finding increasing application in clinical
chemistry and biochemistry Iaboratories wherever it is
necessary to investigate small quantities of material. The book
describes apparatus and general procedures, then deals with
special proaedures for chemical and enzymatic determinations, determlnations of enzyme activities in the biological
fluids and in tissue samples, and finally with ultramicro
methods for the determination of enzymes. The methods
described are nearly all colorimetric, with the cmphasis o n
“optical tests” for the determination of metabolites and enzyme activities.
The book is a valuable aid in the laboratory, particularly for
technical personel. The reviewer would recommend that a
subject index be compiled for later editions, and that the
simplified method given in the appendix for the clinicalchemical determination of glucose in blood should be omitted,
since it does not stand up to critical examination.

Der Arbeitnehmer als Erfinder. Seine Rechte und Pflichten.
(The Employee as Inventor. His Rights and Obligations.)
By 0.Ropke. W. Kohlhammer Verlag, Stuttgart-BerlinKoln-Mainz 1966. 1st Edit., 176 pp., paperback, D M
The author has succeeded in providing an ex remely clear
explanation of the rights and obligations of the employee
(and employer) as they are to be found in IegisIation and
general guiding principles concerning employees’ inventions.
It must, however, be pointed out that, in particular, the
problems of industrial law will cause much difficulty to the
employee-inventor, who generally has little experience in
such matters, and he may easily be led to false conclusions.
The book deals with inventions made in thecourseofemployment, and with free-lance inventions, in the light of important decisions made by the German Federal Supreme Court
and the recommendations of the Arbitration Committee for
Employees’ Inventions. The guiding principles for the remuneration of such inventions are also considered. Further, a
summary is given concerning patent and utility model appli-
cations for free-lance inventions, the utilization of these
protective rights, and the general treatment of employees’
suggestions. The book closes with a section on tax concessions
for the remuneration of employees’ inventions, for income
from free-lance inventions, and for bonuses for suggested
improvements. In the voluminous appendix, the relevant
legislation, ordinances, and guiding principles are given and
various forms are also reproduced. The book can also be recommended t o employers and to those whose profession it is

The Chemistry of Technetium and Rhenium. By R . D . Pea-
cock. Topics in Inorganic and General Chemistry, Monograph 6. Edited by P. L. Robinson. Elsevier Publishing
Company, Amsterdam-London-New York 1965. 1st. Edit.
ix, 137 pp., 14 Figures, 29 Tables. 55s; 27.50 Dfl.
The main purpose of the monograph, which is a Ievlew of the
present knowledge of rhenium and technetium, IS to be found
in the comparison of the chemistry of these homologous
elements. The author not only describes the various classes
of compounds but explains the material in the light of
modern transition-metal chemistry. Understandably, the
greater. art of the bookis devoted to the chemistry of rhenium. The literature is covered up to the middle of 1965;
however, various omissions have been made, even in the better
documented chemistry of technetium. For example, one
searches in vain for information concerning the technically
and scientifically remarkable inhibition of corrosion exhibited
by pertechnate ions. Nevertheless, the book assists the reader
in gaining a deeper understanding of the chemistry of these
transition elements and will prove stimulating reading for
chemists interested in inorganic and radiochemistry.

Introduction to Nuclear Chemistry. By D. J. Carswell, Elsevier Publishing Co., Amsterdam-London-New York 1967,
1st Edit., ix, 279 pp., 69 figures, 23 tables, Dfl. 32.50.
This book is based on lectures which the author gave over
the course of many years at the University of New South
Wales in Australia. It deals with the structure of the atom
and of the nucleus, the laws of radioactive decay, nuclear
reactions, types of decay, the use of physical nuclear methods
in chemistry, such as the Mossbauer effect and nuclear
magnetic resonance, detectors and their mode of action,
radiation chemistry, mass spectrometry. isotope separation,
neutron sources, accelerators, the actide elements, and the
application of radioisotopes in industry and research. The
concluding chapter lists 16 simple experiments which, without
substantial outlay of time nr money, provide an experimental
insight into radiochemistry and nuclear chemistry.
The book is very simply written. Mathematical and abstract
treatment is largely avoided, sometimes with adverse effects.
For example, the reviewer thinks it unlikely that the description of isotope dilution analysis can really be understood.
In a demanding chapter, in which several electronic circuits
are described and in which the mode of action of a diode or
triode is compared with that of a transistor by means of a
circuit diagram, the statement of Ohm’s law is too trivial. In
the chapter “Actinides” the description of the stability of the
individual actinide valences appears to need revision, as well
as a better presentation.
Despite these drawbacks, the book should be particularly
suitable for students who wish to acquire some overall
knowledge of nuclear chemistry and who have no opportunity
to attend lectures on nuclear and radiochemistry. A big help
in understanding the subject matter is the short summary
given a t the end of each chapter. On the other hand, the
price of about € 3.0.0 seems a little high for this introducC, Keller

Nobel Lectures Chemistry 1901-1921 and 1922-1941.
Issued by the Nobel Foundation, Elsevier Publishing
Company. Amsterdam-London-New York, 1966. Volume
1901-1921, xii, 409 pp., several iiiustrations, Dfl 80.-;
Volume 1922-1941 : 53 pp. several illustrations, Dfl. 80.-.
The first Nobel prizes were awarded in 1901. They were, and
in a certain sense still are, a present from the nineteenth
century to the twentieth, for Alfred Nobel died in 1896. It
must have been particularly difficult at the time to find
among the many eminent chemists the one who deserved to
be the first awarded this great distinction. Cannizzaro, Gibbs,
Thomsen and Berfhelot, Arrhenius, Ostwald and A . von Bnyer,
Emil Fischer, and Moissan were considered, and some of
them received the prizes in later years.The majority of the
votes (11 of 20) went to van’t Haff in 1901. It is a pleasure
to read his Nobel lecture today, more than 65 years later.
van’t Huffdeals with osmotic pressure and chemical equilibria
and it is of interest to note that neither here nor in the motivation for awarding theprizesis there an indication of the discovery of the asymmetric carbon atom. This work is mentioned
only in the eulogy - in one sentence. One becomes acutely
aware of the fact that the material that we learn today in the
first few semesters as something self-evident was by no means
self-evident at the beginning of the century.
In 1902 Emif Fischev received the prize for his fundamental
work on sugars and purines, and in 1903 it was Arrhenius’
turn for his theory of electrolytic dissociation (who can
envisage the time when talk of the theory of electrolytic
dissociation was the order of the day?). In 1904 Ramsay was
honored for his discovery of the inert gases, in 1906 Moissan
for his discovery of fluorine, in 1907 Buclrrrer for his demonstration of cell-free fermentation. Self-evident truths today,
but were they 60 years ago?
Anyone with a sense of history will find his money well spent
o n the two volumes of Nobel lectures that have now been
issued by Elsevier. The reader will encounter many important
men who have shaped our modern thinking, but will meet
them in a way different from that in textbooks. One could
say he will meet them on a more personal level.

BiologicaI Chemistry. By H. R . Mahler and E. H. Cordes.
Harper and Row (Publishers) New York-London 1966.
1st Edit., xv, 872 pp., numerous figures and tables, 63 s.
The outstanding contribution made by American workers
to biochemistry during recent years is very largely the result
of this subject gaining a firm place a long time ago in both
medical and natural science faculties of American universities.
In chemistry, as in medicine and biology, biochemistry has
become a pillar of a modern syllabus admittedly with
different aims. While biochemistry (Dhysiological chemistry)
in the field of medicine is characterized by the functions and
pathology of organs, in chemistry i t is thefundamental set
of chemical and physicochemical principles of the life.determining processes. Although all aspects of biochemistry are
interdependent, they can be developed better independently of
one another if the curriculum is adapted to achieve this aim
in the optimum manner. It is clear that a rapid advance in
one section will promote a similar speeding up in another.
This subdivided responsibility somewhat resembles a technique applied for difficult ascents during mountain climbing.
Two ropes are needed for climbing overhanging rocks. One
is used to pull while it runs through the hook fixed above the
climbers, and the second is carried loosely. After the fixing
of the next hook, the second rope in turn takes up the pull.
The above general remarks seemed necessary in order to
characterize the place and importance of this new work. The
book has been written for chemists by chemists. The authors
have done splendidly, and in many respects have achieved a
breakthrough for biochemistry in the part it occupies in
chemical teaching. The book reproduces fairly accurately
