Stereoselective Synthesis
Series: Topics in
Chemistry, Vol. 8.

This book is the eighth volume in the
series Topics in Organometallic Chemistry, and consists of six chapters written
by leading experts in metallocene
chemistry. Although most of the chapters deal with the metallocene complexes of early transition metals such
as Zr and Ti, some recent topics on work
using late transition metals are also
included. The references in all of the
chapters extend up to the year 2002.
Each chapter has a general introduction
to the respective area of research, which
may help beginners to understand the
basics, although this book is aimed at
specialists who wish to have an up-todate summary of recent developments
in this field.
In the first chapter, “Hydrozirconation and its Applications”, P. Wipf and
C. Kendall review the recent examples
of hydrozirconation and its application
to natural products synthesis, focusing
on the development of this subject since
1996, when their last comprehensive
review appeared. As well as describing
a general method for the preparation of
Schwartz reagent, the chapter covers the
synthesis of alkyl- or alkenylzirconium
reagents by the hydrozirconation of
Angew. Chem. Int. Ed. 2005, 44, 6807 – 6808
alkenes and alkynes. Even more importantly, the authors give a good summary
of the synthetic application of organozirconium reagents for the formation of
carbon–carbon and carbon–heteroatom
bonds, including especially the novel
cross-coupling reaction utilizing transmetalation with late transition metals.
The second chapter, “Construction
of Carbocycles via Zirconacycles and
Titanacycles”, by Z. Xi and Z. Li,
describes the preparation of metallacyclic intermediates and their application
to the synthesis of carbocyclic compounds. Most of the chapter is concerned with zirconocene- and titanocene-mediated reactions for the preparation of three- to nine-membered carbocycles.
The third chapter, “MetalloceneCatalyzed Selective Reactions”, by M.
Kotora, gives a brief overview of recent
developments in catalytic organic reactions using cyclopentadienyl metal complexes of both early transition metals
and late transition metals such as Fe, Ru,
Co, Rh, and Ir. The reactions are
classified into seven types. A plausible
reaction mechanism is described and
shown schematically, which helps readers to understand the course of the
E. Negishi and Z. Tan, in the chapter
entitled “Diastereoselective, Enantioselective, and Regioselective Carboalumination Reactions Catalyzed by Zirconocene Derivatives”, describe a highly
selective carboalumination and its application to the synthesis of some natural
products. After a general discussion of
the carbometalation method that has
been developed by the authors, they
give an excellent summary of the application of the zirconium-catalyzed carboalumination of alkenes to the stereoselective synthesis of natural products.
In particular, the asymmetric carboalumination described in this chapter is
useful for obtaining key intermediates
towards natural products.
The following chapter, by N. Suzuki,
is entitled “Stereospecific Olefin Polymerization Catalyzed by Metallocene
Complexes”. The author discusses the
polymerization of propylene, styrene,
methyl methacrylate, 1,3-dienes, nonconjugated dienes, and cyclo-olefins,
focusing on recent examples of the
synthesis of stereoregular polymers.
The last chapter is a review by T.
Takahashi (the volume editor) and K.
Kanno. Under the title “Carbon-Carbon
Bond Cleavage Reaction Using Metallocenes”, the authors discuss stoichiometric reactions involving C C bond
cleavage using metallocene complexes,
and focus on the understanding of these
reaction mechanisms. The C C bond
cleavage reactions are classified into
three types according to the bond
order of the C C bond.
In summary, this book presents valuable information on recent topics in
metallocene chemistry, especially on the
stereoselective synthesis of organic compounds. The book is definitely valuable
for a quick understanding of this field,
and also quite useful to the specialists in
this area.

Integrated Chemical Processes
Synthesis, Operation, Analysis, and
Control. Edited by
Kai Sundmacher,
Achim Kienle, and
Andreas Seidel-Morgenstern. WileyVCH, Weinheim
2005. 540 S., hardcover, 199.00 E.—
ISBN 3-527-30831-8
This book aims to show how one can
simplify the sequence of operations in
an industrial chemical reaction process,
and improve its efficiency, by integrating
techniques (and even new reactors and
reactor components) together. This concept has become known as the “taskintegrated technique”, which is defined
as different techniques integrated within
a single piece of equipment. It is often
illustrated by referring to the example of
a reactive distillation process.
