groups, the planar chirality of the 1.2-substituted ferrocene cannot racemize, both
mono- and diphosphines can be prepared
from the same chiral source. and lastly the
characteristic orange-red color of the ferrocene derivative facilitates chromatographic work-up. Part I ends with a
chapter on “Enantioselective Addition of
Dialkylzinc to Aldehydes Catalyzed by
Chiral Ferrocenyl Aminoalcohols” (Y.

Part 11 again begins with a report on chiral ferrocenes (Ch. 4, G . Wagner and R.
Herrmann). However, it was not clear to
me why this excellent contribution was
not included in Part I, where synthetic aspects had already become an important
part of the discussions.

the above-mentioned article with only minor changes, and without acknowledging
the source. For example, this is clearly
seen in Section 6.4.2, which has only been
very slightly altered and contains the same
literature references in exactly the same
sequence.
But these serious criticisms of Chapter 6 must not be allowed to give the impression that the style is typical of the
book as a whole. On the contrary. the other authors‘ contributions are flawless and
are convincingly presented. Chapter 7 (P.
Zanello) gives a thorough account of the
electrochemistry and structural characteristics of ferrocenes, and includes an extensive tabulation of redox potentials.
Part 111 of the book, with the highly topical title “Materials Science”, describes the
many different aspects of ferrocenes as
materials. ranging from charge-transfer
complexes and magnetic materials (Ch. 8,
A. Togni) through liquid crystalline
compounds (Ch. 9, R. Deschenaux and
J. W. Goodby) to organometallic polymers (Ch. 10. K. E. Gonsalves and X.
Chen). These three chapters are especially
enjoyable to read. as they afford a glimpse
beyond the world of synthetic chemistry.
After reading Ferroceiies it seems well
justified to regard ferrocene as the
organometallic counterpart of benzene in
organic chemistry; this viewpoint helps
one to understand why the range of topics
treated in this book is so broad. On the
other hand, this wide-ranging character
might be seen by some readers as a disadvantage, because the ferrocene chemist,
for whom this book with its wide coverage
would be of greatest interest, does not really exist as such, and the individual chapters are more orientated towards the specialist. Nevertheless. this is a good book,
and for that reason especially it is unfortunate that the high price is likely to restrict
its effective market mainly to libraries and
the above mentioned specialist.

The Chemistry of the Fullerenes. By
A . Him&. Thieme, Stuttgart, 1994.
203 pp., paperback DM 80.00.ISBN 3-13-136801-2
About ten years after the discovery of
the fullerenes, and five years after they became available on a preparative scale, this
book by A. Hirsch now gives us for the
first time a well-written survey of the
rapidly evolving chemistry of this new
allotropic (and molecular) form of carbon. The book covers the most important
published work up to about the beginning
of 1994, lucidly summarizing the results in
nine chapters.
Thc first chapter gives a brief outline of
the discovery of the fullerenes. The author
describes the methods for preparing and
isolating some important fullerenes and a
few of their endohedral derivatives, and
briefly discusses their structure and spectroscopic properties. Chapter 2 is concerned with reduced forms of fullereneC,,,,. which arc of special interest because
ol' thc extraordinary solid-state (superconducting) properties of alkali metal fullerides. Chapter 3 deals with nucleophilic
addition of' carbanions, amines, and hydroxide ions to fullerenes-C,,, and -C,o.
Special attention is given here to the important problems of regioselectivity. the
initial step i n additions to C7,,,and multiple additions to the highly symmetrical
C,,,. Chaptcr 3 is devoted to the important organic cycloaddition chemistry of'
C,,,. with ;I lucid treatment of [4 21-,
+
[3 + 21-, [2 + 21-, and [2 + I]-cycloaddition reactions and the resulting products,
as well as the possibilities for further functionalization of these fullerene derivatives. Chapter 5 is concerned with the
hydrogenation of C,, and C,, , The available data on the many structural variations of constitutionally isomeric hydrogenation products and on their relative
stabilities are systematically reviewed and
are discussed from a theoretical standpoint. Chapter 6 discusses single and
multiple additions of organic and
organometallic free radicals to c,, , and
the free radical-initiated formation of
dimers and polymers. Chapter 7 deals
with complexes formed by fullerenes with
transition metals. Single and multiple additions of this kind can show considerable
selectivity, and structural factors influencing this are briefly discussed. Chapter 8
discusses the complex oxygenation and
oxidation chemistry of C , , and C,,, as
well as reactions with halogens and other
electrophiles. A separate section in this
chapter is devoted to the pioneering work
on the functionalization of fullerenes using osmium tetroxide. In the final chapter
the author summarizes the general features of the reactive properties of C,, and
C j , , and considers likely future developments in the chemistry of fullerenes (e.g.
multiple addition products with controlled constitution. heterofullerenes, endohedral fullerenes) .
This easily readable book gives an excellent insight into the still very rapidly
developing chemistry of the fullerenes. It
is mainly intended for chemists and materials scientists in academic and industrial
laboratories, and provides ;I good coverage of the original literature, including
much that is still novel and speculative. I t
is a highly valuable source of information
both for those already working i n the
fullerenes area and for newcomers. I recommend everyonc who wishes to learn
about the current state of knowledge in
fullerenes chemistry to buy this book.

The surprising patterns of chaos and
complexity are to be found in many areas
of nature and science, examples ranging
from cabbages to coastlines.
Quite often, those who could benefit most
from an understanding of the principles
behind chaos and complexity are denied
access to the power and wonders of the
lield by the mathematical and
unnecessarily convoluted way the topic is
usually presented.
This book makes these sometimes
complicated wonders accessible to
students and professionals alike. Amusing
tales and cartoons are used to explain the
concepts and demonstrate the fascinating
applications of this powerful technique.
