Handbook of Liquid Crystals. By H . Kelker and R. Hatz.
Verlag Chemie, Weinheim 1980. xviii, 917 pages, bound,
DM 420.00.
In recent years the field of liquid crystals has undergone a
tempestuous growth, which is still by no means over. The
reasons for this particular interest in the research and technology of liquid crystals lie above all in their unique electrooptical properties. Now that liquid-crystal materials with a
large meso-phase region and suitable electro-optical parameters have been developed, liquid crystals have found a wide
field of application in electronic displays for clocks, calculators, and measuring instruments and will shortly be used in
motor vehicle instrumentation as well.
This development has been accompanied by an immense
flood of publications, too many even for the expert to take in.
In the light of this situation the present book emerges as a
valuable aid at exactly the right time. It differs from the
monographs that have appeared to date in that it deliberately
does not aim at a textbook-like introduction but attempts to
cover the field as completely as possible. The emphasis is
thus more on the general picture than on details.
One of the authors’ special concerns was to cover the literature. With its more than 8000 citations, the book is of great
informative value, particularly because the titles of the publications are also included. This part is 266 pages long and
constitutes by far the largest section of the book. The literature is practically complete up to and including 1976, and
even covers the bulk of the papers that appeared in 1977.
The following aspects have also received closer attention:
“Chemical Constitution” (Chapter 2) with a detailed (44page) Table of Mesogens, “Behavior in Magnetic and Electric Fields” (Chapter 4), “Optical Properties” (divided into
optically inactive and optically active meso-phases, Chapters
6 and 7), and finally “Nuclear Magnetic Resonance and
Electron Spin Resonance Studies” (Chapter 10, by C. Schumann). In contrast to this, Chapter 14 on “Technical Applications” is rather short (24 pages).
Even though in a rapidly advancing field it is fundamentally impossible to give a definitive picture, the two authors
have succeeded after years of research in creating a work
worthy of regard. The vast wealth of collected material arranged by subject matter in this book never fails to impress.
The clear layout greatly facilitates the use of the handbook:
at the start of each chapter its list of contents is given once
more (even the general index is preceded by a summary!). Increasingly specific subdivision leads the reader step by step
to the required specialist field, so that the book is easy to use
in spite of its extensive scope. All in all, an extremely valuable work that can be recommended without hesitation.

Metal Complexes in Organic Chemistry. By R. P. Houghton.
Cambridge University Press, Cambridge 1979; 308 pages,
bound, € 7.50.
The present book gives a survey of metal complexes in organic chemistry. In Chapters 1 (general principles), 2 (effects
and applications of complex formation), 3 (metal complexes
in addition reactions), and 5 (oxidative addition and insertion) many fields of application are summarized in a synoptic arrangement. Metal-catalyzed polymerization processes
have been deliberately excluded. Aside from the comments
berow it must be borne in mind that the book was written in
D Verlag Chemie, GmbH, 6940 Wernherm, 1980
1978 and accordingly does not reflect the rapid development
of the field. In addition to this, the examples seem to have
been selected only from the point of view of the inorganic
chemist and the materials chemist.
In Chapter 1 there is no mention of the significance of
metals as couplers of n-systems. The wide range of ring closure reactions and H displacements by metalation is not
dealt with. In the discussion of the difficulties of separating
several effects of complex formation no mention is made of
regression analysis. Furthermore, reference should surely
have been made in the “General principles” to the different
thermodynamic conditions within and outside the complex.
In the discussion of the reaction mechanisms one would like
to see a good example of the attack on complex-bound m-systems from the metal and from outside the complex.
In the discussion of the effects and applications of complex
formation in Chapter 2 it should have been mentioned that
the stability of complexes does not always change monotonically as the properties are changed, but can also exhibit minima or maxima. To demonstrate the wide application of metal
complexes for purposes of synthesis, reference should have
been made e.g. to the diethylzinc/Cu variants for the Simmons-Smith reduction and the metathesis reaction.
These critical remarks may serve as an illustration of the
difficulties facing an author engaged in writing a book on a
rapidly developing field.

Metal and Metalloid Amides. By M. F. Lappert, P. P. Power,
A. R. Sanger, and R. C. Srivastava. John Wiley & Sons,
Chichester 1980. 847 pages, bound, € 50.00.
This compact but highly informative book is the first to
present a comprehensive inventory of the field. Up to now
the number and the significance of compounds with the ligands NR’R’ (and also their oligomers and polymers) have
only been the subject of summaries in extract or synoptic
form, and complete documentation of the above amides,
which have grown tremendously in number of the last 25
years, has been long overdue.
To restrict the scope of the work to reasonable limits, compounds with macrocyclic ligands and amides of the nonmetals have been excluded from the discussion of the element
amides, whereas the data on the amides of phosphorus, silicon, and boron and on ionic amides such as M NH 5 have
been kept very concise. Three-quarters of the contents (eight
chapters) are dedicated to the synthesis, the structure, and
the physical properties of the metal amides; in the last quarter typical reactions are discussed over nine chapters. Because
of its systematization, it is precisely this section that exhibits
the advantages of a comprehensive discussion of all metal
and metalloid amides, and will prove particularly useful and
stimulating for those engaged in active research. Thus, in addition to inclusion, protolysis, reactions with hydrides, exchange, and dehydrochlorination reactions as well as Lewis
base and Lewis acid reactions, there is a discussion of applications such as polymerization catalysis.
The larger, referenee-type first part, set out mainly in the
form of tables, is divided into chapters on amides of elements
in the lst, 2nd, 3rd, and 4th main groups (except carbon),
amides of phosphorus, arsenic, antimony, and bismuth and
amides of the transition elements. The sections on amides of
elements in the 3rd and 4th main groups and on phosphorus

amides occupy, corresponding to the importance of these,
more than half of the book; a more far-reaching selection
would have made it possible to shorten the work by 100200 pages. Similarly, the structures have not always been reproduced in the most economical manner, as in Fig. 16, page
495, in comparison with Fig. 4, page 248.
However, criticism of the book is unjustified. Rather, the
authors deserve thanks and an acknowledgement of their
competent description of an important field of molecular
chemistry. Points worthy of emphasis are the well-balanced
arrangement and the painstaking care that can be perceived
even in minor details such as of umlauts. The book finishes
with a brief subject index and a 60-page author index covering some 2500 literature citations up to and including 1978.
It can be recommended not only to chemists working on amides and to libraries, but also-in spite of its price-to all
inorganic and organic chemists and to polymer and structure
chemists who want reliable information on a relatively uniform “inter-disciplinary” class of substances.

Macromolecules. An Introduction to Polymer Science.
Edited by F. A . Bovey and E: H. Winslow. Academic Press,
New York 1979. xiii, 549 pages, bound, $ 39.50.
This is a new textbook compiled from an introductory
course for polymer scientists at the Bell Laboratories, Murray Hill, N. J. offering a short but understandable review of
the current state of the field.
Following a brief introduction (in which reference is already made to such problems as tacticity and mechanical properties), which also contains a very interesting excursion into
the history of polymers, Chapter 2 “Formation of Macromolecules” deals with the most important reactions giving rise
to macromolecuIes. Some important aspects of the reaction
kinetics are discussed in each case. The section on copolymerization kinetics deserves special emphasis. Chapter 3 is
concerned with the clarification of the structure of polymers
by means of physical methods, but here it is assumed that the
reader is familiar with the basic principles of IR and NMR
spectroscopy. The influence of geometric isomerism on the
spectra is explained for some well-chosen examples. At this
point the authors also discuss in comprehensible language
the problems of chain statistics. Chapter 4 considers the thermodynamics of polymer solutions and methods of molecular-weight determination. The mathematics are restricted to
essentials and there are no confusing calculations. Morphological aspects of macromolecules, their physical characteristics such as viscoelasticity, amorphous and crystalline polymers, and transport in polymers are the subjects of Chapters 5
and 6. On the subject of polymer reactions the editors regrettably restrict themselves to degradation and cross-linking. The introduction of functional groups into polymers is
not dealt with, but it would be desirable to include a section
on this topic in a new edition. The work is rounded off with a
chapter on biological macromolecules and their significance.
Every chapter contains a collection of well-chosen literature
references which provide the reader with rapid entry into the
original literature. In a second edition it would be desirable
to give the data in SI units.
The book can be recommended to any reader interested in
polymer science. It represents a valuable and reasonably
priced addition to the reference library of any polymer scientist.
