Metal-arene pi-complexes show a rich and varied chemistry. The
metal adds a third dimension to the planar aromatic compounds and
coordination of a metal to an arene thus not only altering the
reactivity of ring-carbons and substituents but also makes possible
reactions that lead to chiral non-racemic products. This book,
organized in nine chapters and written by leading scientists in the
field provides the reader with an up-to-date treatise on the
subject organized according to reaction type and use. It covers the
wide spectrum of arene activation: from the electrophilic
activation of h6-bound arene by pi-Lewis acid metal complex
fragments, to reactions of nucleophilic h2-coordinated arene
complexes. The preparation of complexes is detailed, as are the
scope, limitations and challenges of reactions in contemporary
pi-arene metal chemistry with special attention given to asymmetric
transformations. The emphasis of the book is on transformations of
interest to organic synthesis and on the use of the complexes as
catalysts or as chiral ligands.
The book is written for academic and industrial researchers in
organic, organometallic, and inorganic chemistry as well as for
advanced chemistry students.
This book presents the most comprehensive analysis of bonding in
polyoxometalates and related oxides based on classical bonding
concepts and the bond valence model. Numerous tables and figures
underline and illuminate the results, making it a valuable
resource.
How did life begin on the Earth? The units of life are cells, which
can be defined as bounded systems of molecules that capture energy
and nutrients from the environment -- systems that expand,
reproduce, and evolve over time, often into more complex systems.
This book is the proceedings of a unique meeting, sponsored by NATO
and held in Maratea, Italy, that brought together for the first
time an international group of investigators who share an interest
in how molecules self-assemble into supramolecular structures, and
how those structures may have contributed to the origin of life.
The book is written at a moderately technical level, appropriate
for use by researchers and by students in upper-level undergraduate
and graduate courses in biochemistry and molecular biology. The
overall interest of its subject matter provides an excellent
introduction for students who wish to understand how the
foundational knowledge of chemistry and physics can be applied to
one of the most fundamental questions now facing the scientific
community. The editors are pioneers in defining what we mean by the
living state, particularly the manner in which simple molecular
systems can assume complex associations and functions, including
the ability to reproduce. Each chapter of the book presents an
up-to-date report of highly significant research. Two of the
authors received medals from the National Academy of Science USA in
1994, and other research reported in the book has been featured in
internationally recognized journals such Scientific American, Time,
and Discover.
The French chemist Marcelin Berthelot put forward a classical and
by now an often cited sentence revealing the quintessence of the
chemical science: "La Chimie cree son objet." This is certainly
true because the largest number of molecular compounds were and are
continuously synthesized by chemists themselves. However, modern
computational quantum chemistry has reached a state of maturity
that one can safely say: "La Chimie Theorique cree son objet" as
well. Indeed, modern theoretical chemistry is able today to provide
reliable results on elusive systems such as short living species,
reactive intermediates and molecules which will perhaps never be
synthesized because of one or another type of instability. It is
capable of yielding precious information on the nature of the
transition states, reaction paths etc. Additionally, computational
chemistry gives some details of the electronic and geometric
structure of molecules which remain hidden in experimental
examinations. Hence, it follows that powerful numerical techniques
have substantially enlarged the domain of classical chemistry. On
the other hand, interpretive quantum chemistry has provided a
conceptual framework which enabled rationalization and
understanding of the precise data offered either by experiment or
theory. It is modelling which gives a penetrating insight into the
chemical phenomena and provides order in raw experimental results
which would otherwise represent just a large catalogue of unrelated
facts.

The aim of this compilation has been to provide a comprehensive,
non critical source of information concerning organometallic
compounds. The scope is limi ed to the compounds containing at
least one carbon-metal bond. The information includes methods of
preparation, properties, chemical reactions, and applications. The
First Edition comprised the literature from 1937 to 1958. The
Second Edition is completely revised and extended through 1964. The
literature prior to 1937 was thoroughly covered by E. Krause and A.
von Grosse in ''Die Chemie der metall-organischen Verbindungen,"
Verlag von Gebrueder Borntraeger, Berlin, 1937. Our work consists
of three volumes. Volume I contains derivatives of the transition
metals of Groups III through VIII of the Periodic Table. Volume II
contains derivatives of germanium, tin, and lead. Volume III
contains derivatives of arsenic, antimony, and bismuth. The
compilation is based on searches through Chemical Abstracts. The
collection of references for 1964 was completed before the Subject
Indexes to Volumes 60 and 61 of the Abstracts were available; thus
some omissions in the coverage of that year are possible. We have
attempted to make the .. coverage of the literature complete in
order that the compilation may have best i1ity to the chemist,
chemical engineer, patent attorney, and editor. In the interest of
brevity, certain numerical data are omitted, but references to the
original literature are given. Yield data are rounded to two
significant figures. Wherever possible, tables have been used. The
entries in the Bibliography section include references to Chemical
Abstracts."
It is said that behind every successful man there stands a devoted
and capable woman. The three famous chemists Perkin, Kipping and
their collaborator Lapworth married three sisters: Mina, Lily, and
Kathleen Holland. The three Holland sisters kept their husbands in
close and very productive collaboration throughout their lives,
thereby greatly increasing their scientific output. They functioned
as a productive scientific family. However, the life and work of
the men is thoroughly documented, but little is known about their
wives. Professor Eugene G. Rochow, a world-renowned scientist,
wrote this biographical historical novel with the help of a
grandson, Dr. Brian Kipping. Professor Rochow did not intend to
write a bare-bones biography. He took care to make the book
factually accurate. Wherever there are no facts, he has not
hesitated to flesh out the account with imagination and actual
experience of others in order to make the text more readable.
The modeling of minerals and silicated materials is a. difficult
challenge faced by Solid StatePhysics, Quantum Chemistry and
Molecular Dynamics communities. The difficulty of such a modeling
is due to the wide diversity of elements, including heavy atoms,
and types of bonding involved in such systems. Moreover, one has to
consider infinite systems: either perfect cr- tals or glasses and
melts. In the solid state a given chemical composition gives rise
to numerous polymorphs, geometricallycloselyrelated. These
polymorphs have very similar energies and related thermodynamical
pr- erties which explain the complexity of their phase diagrams.
The modeling of silicates and minerals covers a wide field of
applications ranging from basic research to technology, from Solid
State Physics to Earth and Planetary science. The use of modeling
techniques yields information of different nature. In the case of
chemical studies, we can mention inv- tigations on catalytic
processes occurring on surfaces and in zeolite cages. These
calculations find possible applications in chemical engineering, in
particular in the oil industry
