To prepare heat-curable acrylic polymers, polyacrylic esters
containing hydroxy groups are mixed with a polyfunctional
1,3,4-dioxazol-2-one (nitrile carbonate) having the formula
( I ) and cured at 120 to 150°C. The polymers containing
hydroxy groups are obtained by copolymerization of acrylic
or methacrylic esters with hydroxyethyl or hydroxypropyl
Esters of N,N‘-ethylenedicarbamicand ethylenedithiocarbamic
acids having the formula ( 1 ) (R, R3=alkyl; R’, R Z = H , lower

Bakterien-, Phagen- und Molekulargenetik (Bacterial, Phage,
and Molecular Genetics). By U . Winkler, R . Riiger, and
W Wackernagel.Springer Verlag, Berlin-Heidelberg-New
York 1972. 1st ed., xi, 285 pp., 15 figures, stitched DM
14.80.
The present book is an attempt to fill a gap among the
German-language practical textbooks for universities. It appears to me that the attempt has been successful. The book
contains a large number of carefully written experimental
procedures for practical courses in molecular genetics. Each
experiment is preceded by an introduction giving the theoretical background. This is followed by aim, materials, procedure,
evaluation, literaturedata, and sometimes exercises for practice
(with answers). Thedescription of theexperiments is so detailed
that the student can profitably work through an experiment
even if he has not carried it out. Each experiment is followed
by a suggestion regarding the recording of the results, a safe
didactic form that can save the course supervisor a great
deal of irritation, but in some cases also slightly relieves the
student of the need to think over the experiment.
Besides many experiments with Escherichia coli and corresponding phages, the book contains a surprisingly large
number of experiments with Servatia marcescens and Serratia
phages. The main reason why so much space is devoted to this
second bacterium is probably that it is one of the author‘s
working organisms. In my opinion it would have been better
from the student’s point of view to extend the experiments with
E. coli, the “pet” of molecular biologists. For example, the
book fails to describe an experiment as important as the
penicillin selection of auxotrophic mutants in E. coli. The
authors are not consistent in their use of abbreviations; alongside the German DNS, RNS, etc., they use English abbreviations such as EDTA and cpm. A detailed subject index should
be regarded as an absolute necessity for the next edition.
The usefulness of the present book to the advanced student
would undoubtedly have been increased by more frequent
indications of the relationships with current research work?
and not just with reviews. The book should be very useful
as a German-language introduction and as a handbook for
3 54
practical courses in molecular genetics. It is to be hoped
that it will give many students an understanding of molecular
genetics“].

Koordinationsverbindungen (Coordination Compounds). By S.
F. A. Kettle. Taschentext Vol. 3. Verlag Chemie, Weinheim
1972. 1st ed., xii, 245 pp., 106 figures and 25 tables, bound
DM 16.80.
The “representative coverage” of a field of chemistry as
large as modern coordination chemistry in a handy volume
of theTaschentext (“pocket text”) series is nowadays practically
impossible without drastic limitations. The book by Kettle,
which was first published in English in 1969 and is now
available in a German translation, is thus confined mainly
to the coordination chemistry of the transition metal ions,
omitting all organometallic, compounds and systems containing metal ions in lower oxidation states. The book is
arranged not according to groups of substances but according to general aspects such as “Nomenclature and Geometrical Structure” (Chapter 2), “Preparation” (Chapter 3), “Stability” (Chapter 4), “Crystal Field Theory” (Chapter 5), “Ligand
Field Theory” (Chapter 6), “Electronic SpectIa” (Chapter 7)
“Magnetic Properties” (Chapter 8), “Other Methods for the
Investigation of Coordination Compounds” (Chapter 9),
“Thermodynamic and Related Aspects of Crystal Fields”
(Chapter lo), and “Reaction Kinetics” (Chapter 11).
The author’s marked interest in problems of electronic
structure and static bonding in transition metal complexes
can be seen e.g. from the fact that Chapters 5 to 8 together
with the “theoretically” oriented Appendix occupy more than
125 of the 242 pages in the book, whereas the treatment
of e.g. equally important topics of reaction kinetics and
mechanisms is clearly too short, covering only 17 pages.

While the section “Quantum-Mechanical Calculation of the
Orbital Angular Momentum” has been added to the Appendix
in the translation, the references to more advanced and additional literature which are given in the English version
have^ unfortunately been omitted. The retention or the updating of these references would have helped to make the otherwise very readable book even more suitable for use as a basis
of, and as supplementary reading for, lectures on coordination
compounds.

Die Analyse der organischen Verunreinigungen in Trink-,
Brauch- und AbwHssern [The Analysis of Organic Impurities
in Drinking Water, Water for Industrial Use, and EMuents].
By W Leithe. Wissenschaftliche Verlagsgesellschaft mbH,
Stuttgart 1972. 1st ed., xii, 172 pp., 21 figs., 22 tables, bound
D M 48.The investigation of impurities in water samples from trade,
Industry, agriculture, and the home is becoming increasingly
important. Owing to the extreme diversity of the substances
and agents with which water bodies are being increasingly
contaminated, it is often necessary to limit the investigation
to the determination of total contents of certain groups or
to use specific methods for individual substances that are
of special interest. In the present book the author tries to
provide the first survey of the very topical analysis of organic
impurities in water.
An introduction to the problems of the contamination of
water, biological self-purification in running water, and the
purification processes in clarification plants is followed by
a very detailed description of methods for the quantitative
estimation of classes of organic material. These include
methods for the determination of organic carbon, the potassium permanganate and bichromate consumptions, and the
biochemical oxygen demanc!. This is followed by a description
of analytical methods for groups of substances and individual
substances, such as fatty acids, cyanides, phenols, detergents,
nitrilotriacetic acid, hydrocarbons (benzines and mi,neral oils),
chlorinated hydrocarbons, pesticides, urea, uric acid, coprosterols, urochromes, humic acids, lignin and ligninsulfonic
acids, and 3,4-benzpyrene.
With this large collection of special analytical methods for
organic contaminants in drinking water, water. for industrial
use, and effluents, the book is a valuable addition to the
standard literature on water analysis, and can be strongly
recommended to all chemists concerned with the investigation
and assessment of water bodies.

Struktur und Reaktivitat polarer Organometalle (Structure and
Reactivity of Polar Organometallic Compounds). By M .
Schlosser. Springer-Verlag, Berlin-Heidelberg-New
York
1973. 1st Edit., x, 187 pp., 29 figures, bound DM 78.-.
This clearly and fluently written book deals with the structure
and reactivity of organometallic compounds of alkali and
alkaline earth metals. It is supplemented by a section on
C-H acidities, to which a very large amount of space (64
out of 187 pages) has been devoted.
Structures in the crystal lattice, the possible aggregations of
polar organometallic compounds in solution (from the dimers
resulting from association via electron-deficient bonds to the
compounds that are dissociated info metal cations and carbanions by solvation), and the connection between aggregation
and reactivity are described in detail. The sections on parameters that influence reactions and on the control of reactions
are particularly interesting.
Angew. Chem. internat. Edit.

Carefully chosen tables, e. y. the scale of “organometallically
projected” C-H acidities of hydrocarbons, as well as very
clear diagrams and a considerable number (447) of references
even to very recent literature further increase the value of
the book to the organometallic chemist who is more familiar
with the other groups of the periodic system.
The book unfortunately contains a number of traps for the
non-specialist and for the student; these traps are partly due
to the quantitative indefiniteness of the adjective “polar”, but
are partly also laid by the author himself when he writes
e.g. “the ideal case of an organometallic reaction is the carbanion process”. While reading this book it would be easy
to forget that it describes only one (extreme) aspect of organometallic chemistry, and the non-specialist could take the part
for the whole.
With and in spite of this reservation, this is a readable, very
stimulating book.

Techniques of Electrochemistry. Vol. 1. By E. Yeayer and A .
J . Salkind. Wiley-Interscience, New York-London
1972.
1st Edit., ix, 581 pp., various figures and tables, bound
L 11.70.
To forestall any misunderstandings, it should be stated that
this book is concerned exclusively with electrochemical experimental and measuring techniques in the laboratory. As stated
in the foreword, preparative methods and techniques for
electrochemical reactions and processes will be dealt with
in later volumes. Another peculiarity of this book, which
is understandable in view of its American orientation, is the
strong emphasis that is placed on the theoretical principles
and the detailed quantitative discussion of the measuring
methods described.
This is particularly noticeable in the first article, by R. G.
Bates, on equilibrium potentials. It is not until the last few
pages that the reader learns anything about the preparation
of reference electrodes. However, the instructions for the platinization of platinum electrodes are not precise and therefore
cannot be used, while the instructions for silver/silver chloride
and calomel electrodes are unnecessarily complicated. The
article by R. Payne on the electrochemical double layer is
much more balanced. The rigid double layer is also referred
to on p. 65 as the Perrin layer and on p. 72 as the Helmholtz
layer. The measuring methods based on the capacity of the
double layer, the surface potential, and voltammetry are described in detail, but almost exclusively for mercury electrodes.
A . Salkind describes the measurement of the true surface area
and the porosity of electrodes from a practical standpoint.
The predominantly non-electrochemical methods, which are
mostly described for the example of lead dioxide, can also
be found in books on catalysis.
The topical field of elect.rochemica1kinetics is finally discussed
in two long chapters. J . Kuta and E. Yeayer describe the
stationary and non-stationary electrical methods. The relationships from themercury drop electrode are discussed in particular detail. However, cyclic voltammetry is also touched upon.
The non-electrochemical methods are summarily dealt with
in the chapter by B. E. Conway. The emphasis here is on
optical methods. The article, which was completed in 1969,
naturally contains little information on fields such as ATR
spectroscopy that have developed rapidly only during the
past few years. Some parts of the article overlap with the
chapter by Payne.
The book is addressed to the electrochemist, who will certainly
welcome a review of measuring and experimental methods
in this field. The book contains no operating procedures.
Little importance is attached to experimental skill. For
