Book Review Physical Methods in Organic Chemistry. Edited by J. C. P. Schwarz

код для вставкиСкачать
on metal amides, imides, and nitrides and ammonium salts,
and on metal amine complexes (metal-salt ammoniates). In the
next seven chapters a systematic survey is given of data on
nitrogen-halogen compounds, on further H-N and HO-N
compounds, o n N-oxides and the corresponding acids, and
on S-N, P-N, C-N, and B-N compounds. In conclusion,
a chapter on the thermodynamics of nitrogen compounds is
given.
It is naturally a gigantic task to try to reproduce even only the
essential aspects of this expansive field on 124 pages with an
acceptable degree of coverage without creating the impression
of only a very superficial treatment. It is therefore not surprising that on reading through the book, one notices a number of unfortunate omissions. For example, it is not enough
to characterize the nitrides of the transition metals simply by
the expression “interstitial or metallic nitrides”. Again in the
treatment of the synthesis of NaN3, the reader misses even a
short discussion of the reaction mechanism (use of 15N to
elucidate it). Furthermore, although many physical propeities have been gathered together into tables, some of these
are absolutely without explanation. This applies, for example,
to the table of successive formation constants for metal amine
complexes in aqueous solution. Without some discussion,
such a table is of little value, especially since the book is not
intended to be simply a work of reference. However, it must
be emphasized that there are many interesting new results to
be found in the book which is characterized by its lucidity in
the presentation of the material and in the mode of expression
in the text. Nevertheless, in the reviewer’s opinion, the present volume falls somewhat short of its aim in filling an existing gap in the literature in this field.

Steroid Chromatography. By R. Neher. Elsevier Publishing
Company, Amsterdam-London-New York 1964. 2nd revised and extended edition, xiii + 389 pp., 31 figs., 78 tables,
linen DM 33.50 (about $8.50).
111this second considerably enlarged edition of his mon3graph, Neher surveys column chromatography (77 pp.), paper
chromatography (1 52 pp.), thin-layer chromatography
(41 pp.), and gas chromatography (36 pp.) of steroids. Following a short introduction to the individual methods, the conventional adsgrbents, solvents for elution, and spray reagents,
c f c . are described, and then the chromatographic behavior of
the various classes of steroids is described, frequently in
readily surveyable tabular form. The examples taken from
the extensive literature in this field have been critically chosen
- no attempt has been made to reproduce a comprehensive
collection of references - and in the appendix more important publications which have appeared this year are given, by
title at ledst. The book provides, particularly in the first two
sections, so many facts that it is a pity that not all are to be
found by using the extensive subject index. Thanks to its detailed description of representative separations and the many
practical hints that it includes, derived from the experience of
its competent author, this book should be of value even to
the experimental worker who is already well versed in this
field.
The layout of the book is excellent, printing errors and incorrect references are few (the solvent systems from Table 63
and the table on page 210 are confused in the text). The formulation of digoxigenin with a 3a-hydroxyl group and the
use of instead of 5 to indicate unknown configurations are
in error throughout; the general remarks made o n pages 56
and 57 contradict in part the data given in the tables.
<
Neher’s book can be highly recommended to all (chcmists,
biologists, and medical practitioners) who are concerned with
the separation or detection of steroids. The time spent in tireful scrutiny of this monograph will soon be repaid many times
by following the instructions given by its author when running
chromatograms.

Physical Methods in Organic Chemistry. Edited by J . C. P .
Schworz. Oliver &Boyd, Edinburgh-London 1964. 1st edit.,
xi + 350 pp., several illustrations and tables, linen 62.10.0
(about $7.00).
This book is intended to appeal principally to students and t o
those chemists who did not have the good fortune to come
into contact with the latest physical methods for determining
structures during their student days. After an introductory
section ( J . C. P. Schworz, 21 pages) which includes infer olio
extensive tables indicating various problems and their methods of solution, there follows a review of the principles conimon to both ultraviolet and infrared spectroscopy ( P . Blndori
and C. Eglinton, 13 pages). Next come chapters on infrared
and Raman spectroscopy (C. Eglinton, 9 1 pages), electronjump spectroscopy ( P . Blodon, 42 pages), nuclear and electron
spin resonance spectroscopy (L. M. Jnckrnan, 42 pages), opticdl rotation [optical rotatory dispersion, circular dichroism,
and the correlation of [rr-ID values] ( J . C. P. Schwarz, 34
pages), molecular-weight estimations (C. T. Greenwood, 3 2
pages), X-ray diffraction methods (C. A . Sim, 30 pages), mass
spectrometry ( R . I . Reed, 17 pages), and dipole moments
( B . L. Show, 15 pages). The best chapters are those on infrared
andultraviolet spectroscopy in which the positions ofthe bands
are explained in detail by recourse to effects that are completely familiar to every organic chemist. The results summarized
in the tables here represent a valuable supplement to larger
monographs on the subject for those familiar with the uses of
infrared spectroscopy. Numerous examples are used to demonstrate its applications, particular attention being paid to
the possibilities of erroneous interpretations. The section on
NMR spectroscopy is also excellent, apart from the fact that
the difference between the coupling constant J and spin-spin
splitting - a point that is especially difficult for the beginner is unfortunately not made clear enough. A review of the methods of O R D and CD, which are constantly finding more and
more applications, especially in the field of natural products,
such as that given in the chapter on “optical rotation” has
so far never appeared in a monograph in German. On the
other hand, in the chapter on mass spectrometry by Reed, it is
astonishing that no mention is made of the present rapid
trend towards application of this technique to the elucidation
of the structures of even the most complex molecules.
This book can be warmly recommended not only to every
student, but also to every older practitioner; this is one of the
monographs that the reviewer would have liked to have
available during his graduate research work.
