Book Review Spectrometric Titrations. Analysis of Chemical Equilibria. By J. Polster and H. Lachmann

код для вставкиСкачать
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.

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.

Part I11 of the monograph describes the apparatus needed
for spectrometric titrations and the electrochemical and
spectrometric techniques involved.
The appendix contains the EDIA program which the authors recommend for use with a personal computer to evaluate relative pK-values (ApK), together with the TIFIT program for iterative curve fitting and statistical analysis of
data.
The authors have set out to critically evaluate the published work on spectrometric titrations which is widely scattered throughout the literature, and to present this in a clear
and easily assimilated form, amplified by results from their
own research in this area.
Perhaps it would be possible in a subsequent edition to
include more detail on methods for determining points of
inflection and stationary points, and measuring the true positions of shoulders in titration curves by repeated differentiation.
The care which has gone into the preparation of the figures, which are excellent from both a visual and a didactic
standpoint, deserves special mention, as also does the overall
quality of production and presentation. This monograph can
be warmly recommended to everyone involved in studying
equilibria and seeking a review of the current state of knowledge in this area. The literature references listed at the end of
each chapter provide a very useful aid to further, more detailed, reading. Although it is pleasing to note that the publishers, notwithstanding the excellent quality of printing and
production, have managed to keep the price down to
DM 0.45 per page, one regrets that not all the students of
chemistry, physics, biochemistry etc. with an interest in the
topic will be able to afford the book. However, it deserves a
place in all university libraries and relevant research laboratories.

Methods for the Oxidation of Organic Compounds - Alcohols,
Alcohol Derivatives, Alkyl Halides, Nitroalkanes, Alkyl
Azides, Carbonyl Compounds, Hydroxyarenes and Aminoarenes. (Series: Best Synthetic Methods, Vol. 8). By A . H.
Haines. Academic Press, London 1988. xx, 467 pp., hardcover, 5 69.50. - ISBN 0-12-31 5502-9
Series such as “Organic Synthesis”, “Organic Reactions”,
or “Reagents for Organic Synthesis”, or more recently computerized data banks of information on reactions, provide
the synthetic chemist with information about preparative
methods which he needs for solving problems of synthesis.
Nevertheless, difficulties often arise from the fact that it is
not always easy to find the required information on chemical
reactions, or to decide on the best method of carrying out the
search. The series “Best Synthetic Methods”, of which the
present book has been published as Volume 8, is intended for
both advanced students and experienced chemists. It aims to
provide them with overviews and critical evaluations, practical advice, and representative examples of important preparative methods, together with guidance on choosing the best
one for the purpose. The author, who has already contributed the second volume of the series on methods for oxidation
of hydrocarbons, has succeeded in meeting the aims of the
series, with the result that this volume too does justice to the
general title “Best Synthetic Methods”.

A major reason for the success of the volume is the orderly
and consistent arrangement of the material according to the
degree of oxidation of the educts. Each of the seven chapters
is further subdivided according to the reagents used. Since
many of the methods described are not restricted to a single
class of compounds, cross-references are provided to other
chapters in which the same reagents are mentioned, thus
providing the reader with additional guidance. The longest
chapter is that on the oxidation of alcohols to carbonyl compounds and carboxylic acids, in accordance with the importance of these classes of compounds. Each of the methods
described in this chapter is prefaced by a general introduction on “Scope and Limitations”. Advantages and disadvantages compared with other reagents are pointed out, and the
numerous variants of one basic method which exist in many
cases are compared. Discussions of reaction mechanisms,
including questions of reactivity, selectivity and stereochemistry provide the reader with additional information to help
in deciding whether a method is suitable in a particular case.
Each sub-section contains examples of detailed preparative recipes in which the theory is applied to optimizing the
practical results. Most of these are carefully worked out
methods which have proved themselves in the exacting area
of natural products syntheses.
The clarity and thoroughness of the experimental details
contribute to the relative ease with which even those with
limited experience can repeat the preparations. Each sub-section is completed by a comprehensive list of references which
includes both review articles and important original papers.
However, the policy of describing only fully proven methods
reduces the topicality of the coverage. The later chapters of
the book deal with oxidation reactions which are of less
importance from the organic chemistry standpoint. However, the author’s balanced and careful treatment of this material succeeds in also providing the user of the book with a
useful account of these classes of compounds and the methods of oxidizing them.
Tables at the end of the book provide a summary of all the
topics covered. These list in a clear form the educts, reaction
conditions, products, yields and key literature references,
enabling the reader to quickly see the main features at a
glance.
