Chemie der Raucherung. By L. Toth. A publication of the
Deutsche Forschungsgemeinschaft. Verlag Chemie,
Weinheim 1982. xi, 331 pp., stitched, D M 68.00.
This monograph provides a comprehensive 100-page literature survey of the smoking of foods (smoke production,
manufacture of smoke condensates, composition of the
curing smoke, the effects of smoking). Then follows a discussion by the author of the investigations of the phenol
fraction of curing smoke (ca. 140 p.) that he carried out at
the Bundesanstalt fur Fleischforschung at Kulmbach (production and condensation of curing smoke, analysis of the
phenol extracts, the influence of the smoking technique o n
the composition of the phenol fraction, phenols in smoke
essences and smoke flavors, phenols in smoked meat products).
Then follows an experimental portion (ca. 25 p.), a list of
all the smoke components so far described, classified according to compound type (306 compounds on ca. 50 p.)
and a bibliography (147 references).
This book is an excellent source of information for every
type of chemical and technological question cqncerning
the smoking of food and hence a solid basis for toxicological discussions. It belongs in every relevant library.

Computeranwendungen in der Chemie. By K . Ebert and H.
Ederer. Verlag Chemie, Weinheim 1983. ix, 359 pp.,
bound, DM 63.00.
Almost every scientifically definable field requires the
participation of another on many occasions. Classically
these are spoken of as auxiliary sciences, a phrase that
sounds somewhat condescending and is often meant to be
so. If a scientist combines this auxiliary science intensively
with his original field, he is often treated as an outsider
and may become an object of amusement. However, it can
happen that what was once an auxiliary science penetrates
large portions of the original and transforms it. Amongst
the natural sciences one only needs to mention the thrust
of mathematics into physics, and chemistry into biology.
Recently mathematics, information science, and computer
science have been extending their role within chemistry.
Theoretical chemistry without mathematics and high performance instrumental analysis (FT-IR, GC-MS, FT-NMR
etc.) without data processing are unthinkable. But techniques of instrumental analysis that are now regarded as
being classical (IR, UV, G C etc.) have also been conquered
by information science and data processing since the application of microprocessors. Nevertheless, the university
education of German chemists takes but slight account of
these trends. This gap has to be filled at the moment by the
further education program of the GDCh (German Chemical Society).
This present book is aimed at filling just this gap. The
hurdle of learning a high level programming language (in
this case BASIC) is skillfully bypassed. Using simple
chemically oriented examples a didactically very clever introduction is presented to the programming of personal
computers. The exemplary programs are concisely and
clearly constructed: commentary, input, calculation and
output. They are written using the minimum of BASIC
which is available with the cheapest personal computer.

However, in certain cases reference to more capable computers would have been sensible; even though they seem
costly, programming time would have been saved.
The severity of both the problems treated and the programming technique has been chosen in a didactically very
refined manner. Numerical integration, equations, linear
systems, differential equations, and nonlinear systems are
treated. In some cases a somewhat more critical presentation of the mathematics would have been desirable. Examples are numerical problems in matrix inversion or the
problem of the linearization of measured data (it is treated
using the Arrhenius equation). In other cases (e.g. Fourier
series) a more detailed presentation of the problem would
have been very useful in the book.
This book can be recommended to every chemistry student as a textbook and a book to work through, as an introduction to personal computers. The simple utilization of
the programs is not to be recommended since it is without
didactic worth. It would be even more senseless, for those
who wish to learn, to purchase the programs ready for use
as diskettes or tapes. The undeniable virtue of this book
lies in the fact that it offers the possibility of familiarizing
oneself independently with the fascinating world of small
computers.

Organic Synthesis. Concepts, Methods, Starting Materials.
By J. Fuhrhop and G . Penzlin. Verlag Chemie, Weinheim
1983. xi, 355 pp., bound, D M 78.00.
With the increasing importance of chemical synthesis,
the problems of synthesis planning and execution have become focuses of interest. The number of recently published
books, dealing with the strategy and techniques of synthesis, mirror this development. This book is intended to provide advanced students and research chemists with knowledge of educts, target molecules and the concepts and
methods concerning their transformation.
The first chapter deals with the construction of carbon
chains and carbocycles, whereby the authors apply Corey’s synthon concept including the idea of “Umpolung” as
a useful heuristic principle. Here, as in many other publications, there is no strict differentiation between a synthon
as originally formulated by Corey and the reagents corresponding to this concept. It is inevitable that this point of
view-analysis of the target compound into synthonsshould lead to the neglect of one of the most important aspects of organic chemistry, namely stereochemistry.
The steric course of the reaction is then discussed using
individual examples. Some methods of carbon-carbon
bond formation, e.g. the Wittig reaction, are thoroughly
discussed mechanistically, at the same time drawing stereochemical conclusions. Just as thorough a discussion of
the aldol reaction would have been desirable, since, in its
many newly developed variations, it vividly demonstrates
the powerful nature of organic chemical synthesis.
The pattern is similar in the next chapter which deals
with the transformation of functional groups. The Sharpless epoxidation for the stereoselective synthesis of polyhydroxy compounds is amongst the omissions here; no account is taken of recent highly selective reducing agents or
microbiological reductions; some important protecting
