Book Review Preparative Polar Organometallic Chemistry. Vol. 1. By L. Brandsma and H. D. Verkruijsse

In these cases, therefore, one needs to use the separately
bound names index, which contains all the systematic names
and common trivial names that are listed in the main work.
Here it is worth noting that many of the names from the
older literature have been altered to conform with modern
rules of nomenclature. The index volume also contains a
molecular formulas index, a list of CAS Registry Numbers,
and an index of compound types. In this each alkaloid is
assigned to one or more of 296 groups arranged mainly according to structural types, which enables one to easily obtain a complete survey of alkaloids of a particular type, e.g.
mold alkaloids, alkaloid-N-oxides, tropane alkaloids, or
compounds related to morphine.
The species index, containing nearly 20000 references, is
without doubt an especially useful feature, even though it
has a few gaps--for example, under the anhalonium types
the important alkaloid mescalin is not listed. Under the botanical name Corfinarius orellanus one finds, as expected, a
reference to orellanin. However, the peptide structure for
cortinarin, which although it seems unlikely has not yet been
disproved, is not mentioned here-ould
this be a result of
critical selection?
With such an all-embracing definition of alkaloids it is
inevitable that the boundaries are somewhat fluid, and this
unavoidably leads to some inconsistencies. For example, although indirubin is included, the better-known indigo isomer is absent; also not mentioned are indoxyl and isatin.
However, one hardly expects to find these compounds in a
book on alkaloids in any case; their omission is therefore a
trivial matter in this extremely up-to-date survey of the literature on alkaloids, which is the most complete printed compilation available anywhere on the subject. Of course, it goes
without saying that a mammoth work of this nature, which
is comprehensive and up-to-date to a degree otherwise only
achieved in computerized data banks, is priced accordingly.
To read this book is aesthetically pleasurable, in addition to
the information that it yields; it should be in every library
which is concerned with natural products.

Preparative Polar Organometallic Chemistry. Val. 1. By L.
Brandsma and H . D. Verkruijsse. Springer, Berlin 1987.
240 pp., paperback, DM 78.00. - ISBN 3-540-16916-4
When one compares the increase in the library budget (at
any rate, that in Marburg) with the increase in the cost of
journals and books, the effect in recent years has been to cut
resources, making it necessary to exercise special care over
the purchase of new books. Can we or can we not afford a
certain book? In this case the answer must be an unqualified
“yes”, if only because, pursuing this economic theme, the
book by Brandsma and Verkruijsse enables one to save money. The authors have produced an extremely practical book,
a “laboratory manual”, as they call it, for chemistry students
and for chemists in industrial and university laboratories.
Nothing has been left to chance; all the laboratory recipes
have been tested several times by the authors themselves,
who have a great deal of experience in the field of polar
organometallic compounds. Everyone who has ever worked
with a recipe which is not reproducible (or which does not
work at all!) will appreciate what it means to use one that has
been tested and optimized.

The book deals with polar organometallic compounds (intermediates) obtained from sp2 compounds. Chapter ’I gives
an introductory general survey entitled “0rganomet:tllic
Reagents, Solvents and Laboratory Equipment”. This includes useful hints on the safe handling of such compounds,
and also on their disposal. The following chapters are: Chapter 2 “Reactivity of Polar Organometallic Intermediates”,
Chapter 3 “Metallated Olefinic and Allenic Hydrocarbons”,
Chapter 4 “Metallation of Hetero-Substituted Unsaturated
Systems”, Chapter 5 “Metallated Hetero-Aromatic Compounds”, and Chapter 6 “Metallated Aromatic Compounds”. There is a very useful appendix consisting of tables
from which the reader can find suitable methods for preparing any particular polar organometallic compound, and for
reacting it with an electrophilic species. Another table lists
typical reaction conditions with a wide variety of electrophiles.
In summary, anyone who wishes to save money and avoid
irritation in preparing and carrying out reactions with polar
organometallic compounds should buy this book by Brandsma and Verkruijsse. The money will be well spent.

Spectrometric Titrations. Analysis of Chemical Equilibria. By

The meaning primarily attached to the word “titration” is
the method introduced by Gay-Lussac for the quantitative
determination of dissolved substances. The end-point of
such a titration is usually determined using an indicator
which undergoes a color change. However, it was soon recognized that this method can be used to investigate a wide
variety of other equilibrium systems. The changes in the
physical condition of the system are observed in either a
stepwise or a continuous fashion by means of suitable instruments which detect changes in variables such as pH, electrical conductivity, optical density, fluorescence or optical rotation. From the resulting titration curves it is then usually
possible to calculate the equilibrium constants, which play a
fundamental role not only in chemistry and physics, but also
in biochemistry and medicine, pharmacy and toxicology,
and other areas.
Part I of this book deals with the basic theory and methodology of spectrometric titration. The topics covered are the
classification of the various methods, the graphical treatment of the experimental data, multiple wavelength spectrometry, and thermodynamic and electrochemical principles.
Part I1 discusses in detail the formal treatment of titration
systems and the calculation of results. Acid-base equilibria
involving one, two, three and still more stages are considered, and methods of treating the data by iterative curve
fitting and statistical analysis are described. For non-overlapping multi-stage titration systems it is necessary to add an
external standard proteolyte whose pK-value is known very
accurately; from the simultaneous titrations one can then
determine a relative pK-value for the equilibrium being investigated. Branched acid-base equilibria, metal complex
equilibria, association equilibria and redox equilibria are
also considered.
