dust is still an extremely useful method in structural investigations when known rearrangements are borne in mind. B. C.
L. Weedon reviews the applications of alkali fusion and the reactions that occur thereby. Relatively unknown reactions,
such as the alkyl transfer to ketones, special dehydrogenations
of alkoxides, and the demethylation of methoxylated phenols
are mentioned. J. K. N . Jonesand M. 3. Perry discuss methods
for degrading polysaccharides and methylated polysaccharides. K . W . Bentley describes the application of conventional
methods of cleaving C - 0 and C-N bonds mainly in the
alkaloid series. The reviewer welcomes the inclusion of the
little known cleavage of N-CH3 bonds with azodicarboxylic
esters discovered by 0. Diels and of the @elimination with
LiAIH4. E. Y . Spencer gives a thirty page review of methods
for the hydrolytic degradation and elucidation of the structures of polypeptides and proteins, including a discourse on
oxidative procedures. K . T. Ports illustrates the application of
known methods of cleaving C = C bonds with examples from
the chemistry of natural products. The interesting cleavages
that occur with alkaline H202 are relatively unknown. A
second article by K . W. Bentley o n C = C fission reports
mainly on common methods; the examples given of abnormal
cleavage with ozone are highly instructive. The chapter by
N . Polgar on methods for shortening side chains and longchained compounds is also very useful as it describes relatively unfamiliar reactions.
Here brevity does not permit a closer appraisal of the excellent article (150 pages) by 3. Belleau oil the allocation of
steric configurations to natural products using chemical methods. This article also describes the latest data o n reaction
mechanisms and can be recommended as the basis of lectures
on stereochemistry. In the final article, P . de Mayo writes a
most intriguing review of rearrangement reactions that occur
with natural products. Only one (see p. 1095) of the few printing and formulae errors is not immediately recognizable: here
a n attacking proton is drawn directly above a n angular
methyl group. This volume deserves a hearty recommendation.

Infrared Band Handbook. Edited by H. A . Szymnnski. Plenum
Press, New York 1963. 1st Edit., xii + 484 pp., linen $7.50.
This book is a catalogue of over 8500 infrared bands in the
region between 3610 and 617 cm-1, measured o n over a
thousand substances. In the main part of the volume, the
bands are arranged in order of decreasing wave-number. The
information for each band comprises, as far as possible, substance, nature of sample measured, resolution of instrument,
type of vibration, band intensity, and reference. The book contains also a substance index and correlation tables for methyl
deformation vibrations and C-N valence vibrations, since
these vibrations are not included in the main section. The
literature references have been restricted to 25 sources covering the period up to 1961. The principal source evaluated is the
American Petroleum Research Institute, Project 44 catalogue.
Annual supplements costing $7.50 are planned to cover the
region down to 250 cm-1. The book is a valuable aid for the
identification of unknown substances and for the solution of
problems of band assignment.

theories and for development of more refined concepts. In this
first of two volumes on the “Oxidation of Metals” J . Benard
and a number of collaborators have attempted to give a detailed account of the fundamental principles involved, without omitting any relevant material. A brief glance at the coiitents of the various chapters may serve to illustrate this point.
Chapters 1-5: Metal surfaces, adsorption equilibria, the kinetics of adsorption and chemisorption, the structure of
chemisorption layers and their influence o n the properties of
the underlaying metal (J. BPnard). Chapters 6-8: Nucleation
processes, the growth of thin layers and their orientation ( J .
Benard, J . Bardollc, and F. Bouillon). Chapters 9-1 I : Thicker
layers, methods of investigation and results, diffusion theory
of layer formation ( G . Valensi). Chapters 12-15: Thermodynamics and kinetics of the oxidation of alloys, internal oxidation (J. Morenu and J . BPnnrd). Chapter 16: Real structure
of oxides, mechanical properties, dislocations, etc. ( M .
Cagnet). Tables of crystallographic, thermal, and mechanical
properties of metal oxides are also given.
The individual contributors d o not always adopt the same
approach to their readers. Thus, for example, a detailed derivation of the law of diffusion is given (p. 228), but sometimes
simply the results of rather complex theorems are given, e . g .
for internal oxidation. Nevertheless, the book offers an excellent provocative and modern survey of the subject, and
topics that are all too frequently neglected (e.g. the morphological and mechanical properties of metal/metal oxide systems) are considered, as is to be expected from this editor and
his coworkers. English, French, and German literature has
been covered thoroughly and uniformly until 1960 (1052

Steroid Reactions: An Outline for Organic Chemists. Edited
by C . Djerassi. Holden-Day, Inc., San Francisco 1963. 1st
Edit., vi + 657 pp., linen $9.75.
C. Djerassi maintains that the increasing profusion of publications connected with the field of steroids has led many chemists who are not familiar with this subject to abandon the
practice of reading articles devoted to it. This is regrettable
insofar as there is hardly a chemical reaction that has not
been applied to steroids. Furthermore the reactions applied
have frequently led to particularly lucid results because of the
relatively precise knowledge of the structures, conformations,
and reactivities of steorid derivatives. In order to break the
soil of this fallow field and make it available even to nonsteroid chemists, 16 post-graduate students at Stanford University undertook to arrange 14 special aspects of the subject
i n t o order in the form of formulae schemes under Djerassi’s
guidance; the appropriate reaction conditions, yields, and
literature references are given for each reaction. The data
include the protection of carbonyl and hydroxyl groups,
selective oxidation of polyhydroxysteroids, the introduction
of fluorine into the steroid system, the production and dehydrohalogenation of a-bromo, or-chloro, and or-iodo ketosteroids, erc. Apart from short introductions before the chapters, written text has been completely replaced by formulae
and reaction schemes. Thus it is simple for the user of the
book t o survey the general picture, and this helps him to find
any desired reaction rapidly. Since the work done by the
students has been checked and supplemented by experienced
steroid chemists in large American firms, the result is an excellent review volume which undoubtedly fully achieves its
aim of providing a rapid guide to the entire subject and which
will therefore soon acquire many friends. The book fills an
obvious gap, even though it is not completely free from errors;
one must expect this when one considers the abundance of
material discussed. However, the reviewer doubts whether it
will influence many non-steroid chemists into investigating
the ever increasing amount of steroid literature. In any case,
it will certainly be often consulted by the specialist in this field.
