Organolithium chemistry occupies a central position in the
selective construction of C-C bonds in both simple and complex
molecules. Paralleling the surge of interest in methods for
asymmetric synthesis, the use of organolithiums in enantioselective
synthesis has witnessed spectacular advances in a little over a
decade. This volume is the first dedicated to a comprehensive
coverage of this important area. It is designed to provide graduate
students and researchers with a rich source of essential
information on synthesising molecules in an enantioselective manner
using organolithiums, and be an inspiration for future
developments. Following an overview chapter summarising the key
milestones, successive chapters, each written by leading experts in
their field, critically survey all the major areas of progress.
Two decades have passed since the original discovery of recoilless
nuclear gamma resonance by Rudolf Mossbauer; the spectroscopic
method based on this resonance effect - referred to as Mossbauer
spectroscopy - has developed into a powerful tool in solid-state
research. The users are chemists, physicists, biologists,
geologists, and scientists from other disciplines, and the spectrum
of problems amenable to this method has become extraordinarily
broad. In the present volume we have confined ourselves to
applications of Mossbauer spectroscopy to the area of transition
elements. We hope that the book will be useful not only to
non-Mossbauer special ists with problem-Oriented activities in the
chemistry and physics of transition elements, but also to those
actively working in the field of Mossbauer spectroscopy on systems
(compounds as well as alloys) of transition elements. The first
five chapters are directed to introducing the reader who is not
familiar with the technique to the principles of the recoilless
nuclear resonance effect, the hyperfme interactions between nuclei
and electronic properties such as electric and magnetic fields,
some essential aspects about measurements, and the evaluation of
Moss bauer spectra. Chapter 6 deals with the interpretation of
Mossbauer parameters of iron compounds. Here we have placed
emphasis on the information about the electronic structure, in
correlation with quantum chemical methods, because of its
importance for chemical bonding and magnetic properties."
The aesthetically pleasing molecular architectures of fullerenes
and nanotubes are appealing not only because of their beauty but
also because they are responsible for the many unprecedented
chemical and physical properties of this compound class. Although
succession of exciting new discoveries continues unabated fullerene
research has become a mature science. It is now possible to predict
fullerene chemistry, to design new structure variations like open
fullerene clusters, heterofullerenes and endohedral fullerenes, and
to develop fullerene materials and modified nanotubes with high
potential for technological applications. This volume represents
the state-of-the-art of fullerene research, focussing on areas
showing high potential for future growth and practical
applications. The authors are leading scientists whose groups are
making major contributions in the field.
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.
