and horizontally with gcneral chemical and biological
chapter headings, individual quinones occurring in subheadings.
Thus, in contrast to its title and pretty dust-cover, and in
spite of its si7e, this book is restricted substantially to
strongly lipophilic quinones with isoprenoid side chains. For
these compounds, which are important as constituents of
biologically functioning particles, it provides comprehensive
and valuable documentaiion. ~. The reader is advised to
begin at page 89.

Oligosaccharides. A comprehensive account of all known
sugars of the oligosaccharide class of compounds. By R. W.
Bailey. Pergamon Press, Oxford-London-New York-Paris
1965. 1st edit., vi 178 pp., bound S 3.0.0.
tined himself almost entirely to the Anglo -Saxon and particularly the English literature.
On the other hand, oxidations occurring in inorganic chemistry are handled better and more completely. Even the division of the material, with its chapter headings “Cation,cation
oxidations”, “Cation,substrate oxidations”, ere., is better
suited to inorganic than to organic oxidations since the latter
often involve neutral molecules.
The claim on the dust-cover that “Without doubt, this is an
exceptionally informative treatment of the suject for all chemistry students reading for Honours Ph. D. degrees. It will also
be of value to industrial chemists concerned with oxidation
processes” seems to the reviewer to be greatly exaggerated.

The development of chromatographic methods for separation
of oligosaccharide mixtures has led, particularly in recent
years, to the isolation of numerous new compounds of this
type. Since the results are recorded in journals appertaining
to different disciplines the increasing number of new oligosaccharides makes it continually harder to determine whether
a particular compound has or has not been described. The
object of the present book is to eas3 this situation.
Nomenclature and the methods of isolation and determination
of structure are first reviewed. The main part of the book
contains a systematic list of all (about 480) the oligosaccharides that contain up to ten monosaccharide units and were
known up to the end of 1962; this occupies some 100 pages.
Short entries record the physical constants, source, isolation,
and, as far as realized, the chemical synthesis. Each oligosaccharide is given a number which is used in the indexes.
An enormous amount of material (over 1000 refeyences to
original papers) has been brought together in this book,
sifted, and splendidly handled The classification is clear and
easy to follow, and the presentation intelligible despite its
concise form. It affords a source of information that is rapid
and fully sufficient for first orientation, this being aided by
the excellent zrrangehent of the index. For instance, “Compound N o 337” is found in the index of trivial names under
raffinose, gossypose, and melitriose, and again in the general
subject index as 6G-a-galactosylsucrose (the name being abbreviated according to W. J . Whelan’s proposal) among the
oligosaccharides related to D-glucose, D-galactose, and Dfructose. This book is essential for the chemist working in the
field and should be in every library. It only remains to be
hoped that the classification and noqenclature used in it will
be adopted, not only in the specialist journals, but also in
textbooks.

Oxidation Mechanisms. By T. A . Tioney. Butterworth & Co.;
Ltd. London 1965. 1 st Edit., viii + 207 pp., 35 s. (about
5 4.7).
The two recent monographs by Waters and Stewart dealing
with oxidation mechanisms are now followed by a third,
from a New Zealand author. It is similar i n size to its piedecessors but differs in that inorganic ions as well as organic
compounds are treated.
The organic part is certainly too short. Mulriprade, Hnrries,
Rieche, 0. Dimroth, Hock, Bartlett, RoFek, Swern, Prileshajew, and Teiiber are missing ffom the author index of about
600 names, entries such as cumene, decalin, peracids, and
quinone from the subject index, and biological oxidation is
not mentioned at all, the reaction of ozone with olefins is
omitted, and the enormous influence of the configuration of
a glycol on the velocity of its fission by periodate or lead
tetra acetate is not mentioned; the reader is not told that the
reaction with O s 0 4implies a cis-hydroxylation. This list could
be expanded. One gets the impression that the author has con-

H igh-Temperature Compounds of Rare Earth Metals with
Nonmetals. By G. V. Sumsonov. Consultants Bureau
Enterprises, Inc., New York 1965. 1st Edit., xiii + 280 pp.,
numerous figs., $ 17.50.
This monograph is an expanded and improved English translation of the Russian edition that appeared in 1964. The
author, who is represented by many contributions to this field,
deals with borides, carbides, nitrides, silicides, and sulfides of
scandium, yttrium,lanthanum, and lanthanides. Each chapter
is divided into sections: structure and properties, general
methods of preparation, description of all the compounds,
areas of use, literature citations. For example, in the chapter
on carbides one finds :
( I ) Crystal structure of compounds of the types M3C, MC,
M2C3, and MC2; densities; specific electrical resistance; magnetic behavior. There are comparative observations on variation of the metallic component, and general viewpoints are
brought out.
(2) Review of preparation from M
+ C or M2O3 + C.
(3) Reports on all the !mown carbides, from Sc to Lu; preparation and properties; phase diagram for Laic. Here the
monograph takes o n the character of a list of references.
(4) Short indications of possible uses.
The title “High-Temperature Compounds.. .” leads one to
expect extensive applications in the hjgh-temperature region.
But this development peters out quite early. Often only laboratory experiments re reported and proposals mentioned. Information about the use of hexaborides (LaBs) as cathode
material is somewhat more extensive; and additionally the
use of the substances described as semiconductors, neutron
absorbers, and crucible materials is considered.
The book makes the impression of being complete (references
up to 1964) and expertly compiled. It can afford valuable information to those interested in this field. Printing and production are good.

Stereochemistry, Mechanism and Silicon. By L. H . Sommer.
McGraw-Hill Book Comp., New York-St.Louis-San
Francisco-Toronto-London-Sydney 1965. 1st Edit., xvi +
189 pp., 78 s. (ca. $ 9.50).
Monographs on organosilicon chemistry have hitherto been
of the comprehensive, general type. The rapid growth of
knowledge has, however, brought a further need for monographs o n special problems and partial areas.
Therein lies the value of L. H . Sommer’s book o n the relations
between stereochemistry and reaction mechanism at the silicon center of organosilicon molecules. The author is Professor of Chemistry at Pennsylvania State University and has
long been known for his valuable contributions to the preparative and theoretical chemistry of organosilicon comAngew. Chem. internat. Edit.
