This book contains the proceedings of the Symposium on FT-IR
Characterization of Polymers, which was held under the auspices of
the Division of Polymer Chemistry, American Chemical Society (ACS)
during the annual ACS meeting in Philadelphia, August, 1984. The
content of each paper has been substantially extended from the
papers presented during the conference. Due to the accidental,
irrecoverable loss of the entire contents of the book by the
computer system used for editorial purposes, the publication of
this book has been delayed more than one year over the initial
scheduled date. It has been a continuous, frustrating experience
for the editor as well as for the authors. An extended Murphy's
law, -anything can go wrong goes multiply wrong- has been
demonstrated in editor's office. It necessitated, otherwise
unnecessary, repeated proof reading during which time the editor
had valuable experience ~n familiarizing himself with each paper
much more than usual. The papers in this book are state-of-the-art
even after such a delay. It is the authors pride and integrity
toward the quality of each paper that makes the value of this book
long lasting, while responsibility of the loss of any timeliness
rests at the editor's hand. For the purpose of official records,
submission and acceptance dates must be stated. All papers had been
submitted by September, 1984, and had been accepted for publication
by November, 1984, after the critical review processes.
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.
General The making and breaking of carbon-metal bonds is
fundamental to all the p- cesses of organometallic chemistry and
moreover plays a significant role in - mogeneous as well as
heterogeneous catalysis. This rather blunt statement - phasises the
extent to which a proper understanding of the structure, energetics
and reactivity of C-M bonds is at the core of the discipline. In
order to accept it, a proper definition of the terms involved is
required. Quite simply we define the metal-carbon bond in its
broadest sense to embrace carbon linked to transiti- metals,
lanthanides and actinides, and main group metals. We do not dist-
guish between formally covalent single or multiple bonding on the
one hand and q-bonding on the other. In the studies to be described
in the following chapters, the emphasis will be on transition metal
complexes and insofar as the fun- mentals come under scrutiny,
simple metal alkyls or related species (metal al- nyl, alkynyl,
aryl, or allyl) will play an emphatic part. The central role of
metal alkyls and their congeners and especially the role of their
metal carbon linkage in homogeneous catalysis may be appreciated by
considering some key reaction steps leading to their formation or
breakdown. There follows a few prominent examples of transition
metal mediated stoichiometric or catalytic processes: - In
homogeneous hydrogenation of double bonds, the stepwise reaction of
an q2-coordinated alkene with dihydrogen gives first an alkyl metal
hydride, and then the decoordinated alkane by elimination.
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.

It is 25 years since the seminal papers describing the
relationships between the skeletal geometrics and closed shell
electronic requirements of metal clusters were originally
published. The electron counting rules which developed from these
papers, are now to be found in all undergraduate inorganic
textbooks. This volume provides a contemporary account of recent
applications of the methodology and the mathematical foundations of
the rules. In addition it describes how it is possible to
accomondate acception to the rules within a wider framework. The
authors are the foremost authorities in the field and give a broad
introduction to the area.
Although the research actIvItIes of dyestuff chemists worldwide
have been influenced to a great extent, in recent years, by the
need to respond to a variety of environmental issues associated
with the manufacture and application of synthetic dyes and
pigments, a significant level of targeted research continues to be
devoted to new chemistry aimed at enhancing the technical
properties of dyes in commerce. This book is a presentation of
various aspects of basic research conducted during the past decade
but not reported in the recent review literature. The coverage
herein is unique in that it emphasizes systematic approaches
commonly utilized in the design and synthesis of dyes and pigments
and the required intermediates. While it is well known that certain
transition metals are important in the synthesis of technically
viable metallized dyes for polyamide and protein fibers, these
metals are demonstrated in Chapter 1 also to be effective agents in
the regiospecific placement of substituents into azo compounds. The
scope and limitations of this chemistry are presented. In other
synthetic work, a description of the different processes employed
to produce the major families of reactive dyes is presented. In
Chapter 4, special attention is given to reactive dyes containing
more than one reactive group, and to the more recent developments
in the field. The two chapters which follow provide a review of the
recent literature pertaining to novel chromophores and dyes for the
D2T2 process, respectively.
