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-
