Book Description
As an environmentally benign element, bismuth has found more and more applications in advanced materials. Our research is aimed at two aspects of bismuth oxide materials. Our goal is to provide precursors for bismuth oxide. Bismuth trioxide is an important component of many ferroelectric materials, but the development of bismuth precursors is still very limited. Another goal of our research is to synthesize homogenous model systems for the catalyst of the SOHIO process. In the SOHIO process, propene is selectively oxidized to acrolein or selectively ammoxidized to acrylonitrile. The detailed mechanism of the process remains controversial. Several molybdenum and Mo/Bi bimetallic systems have been studied, but no bismuth model has been reported before. In the second chapter, I reported the isolation and full characterization of twelve bismuth aryloxide complexes, Bi(OAr)3. The substituents' steric effect and electronic effects on the synthesis were studied. Phenyl substituents were utilized to study the bismuth-arene interactions. I also synthesized complexes with allyl or benzyl substituents very close to the bismuth center. These complexes can be good model systems to study the SOHIO process. The bismuth aryloxides we synthesized can also be used as sol-gel precursors for bismuth oxide materials. In the third chapter, I reported the synthesis of bismuth aryloxide amides Bi(OAr)n(NR)3-n, using a ligand exchange method (Bi(OAr)3 + Li(NR)---Bi(OAr)n(NR)3-n). The ligand exchange method is versatile for several kinds of bismuth aryloxide as well as an antimony aryloxide. The bismuth aryloxide amides were spectroscopically characterized, and four of them were characterized by X-ray diffraction. The bismuth aryloxide amides are also good precursors for Bi2O3 materials. They are volatile, light stable and low melting, with excellent solubility and tunable thermal stability. In the fourth chapter, I reported the isolation of ten monosubstituted alkali metal calix[8]arene complexes. Preliminary results were also obtained for reactions of the mono substituted alkali metallocalix[8]arenes with several kinds of bismuth compounds.

Book Description
The ASI workshop on "Selectivities in Lewis Acid Promoted Reactions" held in the Emmantina-Hotel in Athens-Glyfada, Greece, October 2-7, 1988 was held to bring some light into the darkness of Lewis acid induced processes. As such the workshop reflects some current trends in organic synthesis, where Lewis acids are becoming a powerful tool in many different modern reactions, e.g. Diels-Alder reactions, Ene reactions, Sakurai reactions, and in general silicon and tin chemistry. The objective of this meeting was to bring together most of the world experts in the field to discuss the major reactions promoted by Lewis acids. Organic synthesis will play a major role in this book connected with some fundamental mechanistic work on allylsilane and -tin chemistry. Both natural product synthesis and unnatural molecules are presented in the chapters. The book presents all the 15 invited lectures and the contributions of 15 posters. I am confident that the material presented in this book will stimulate the chemistry, which has been discussed on our meeting, around the world. The meeting and the book were only possible through a grant of the NATO Scientific Affairs Devision and financial support by the following companies: Kali Chemie (Hannover, W-Germany), E. Merck (Darmstadt, W-Germany), Sandoz (Basel, Switzerland), Schering (Berlin, W-Germany).

Book Description
This volume in the series Chemical Thermodynamics provides a comprehensive review and critical evaluation of experimental data available for the chemical thermodynamics of inorganic compounds and aqueous species and complexes of technetium. The objective of the reviews in the series Chemical Thermodynamics is to provide a set of reliable thermodynamic data that can be used to describe the behaviour of the elements reviewed under conditions relevant for radioactive waste disposal systems and various geochemical environments. Data and their uncertainty limits are recommended for the formation energies, enthalpies and entropies of selected aqueous complexes, solids and gaseous compounds containing technetium. The data are internally consistent and compatible with the CODATA Key Values, as well as with the data in the earlier volumes in the series Chemical Thermodynamics. The book contains a detailed discussion of the selection procedures used

Book Description
The series Topics in Organometallic Chemistry presents critical overviews of research results in organometallic chemistry. As our understanding of organometallic structure, properties and mechanisms increases, new ways are opened for the design of organometallic compounds and reactions tailored to the needs of such diverse areas as organic synthesis, medical research, biology and materials science. Thus the scope of coverage includes a broad range of topics of pure and applied organometallic chemistry, where new breakthroughs are being achieved that are of significance to a larger scientific audience. The individual volumes of Topics in Organometallic Chemistry are thematic. Review articles are generally invited by the volume editors. All chapters from Topics in Organometallic Chemistry are published OnlineFirst with an individual DOI. In references, Topics in Organometallic Chemistry is abbreviated as Top Organomet Chem and cited as a journal

Book Description
Joseph Chatt was a pioneering figure in coordination chemistry. Intended as a record of Chatt's life, work, and influence, this book begins with a description of Chatt's career presented by co-workers, contemporaries, and students, then goes on to show that many of today's leading practitioners in the field have been influenced by Chatt. The latest research in coordination chemistry is presented to highlight Chatt's continuing legacy, in sections on the synthesis and reactivity of hydrido and dihydrogen complexes, the chemistry of phosphines, transition metal complexes of olefins and related isolobal ligands, chemistry related to dinitrogen complexes, the biological work of the ARC unit of nitrogen fixation at the University of Sussex, and patterns and generalizations in stability and reactivity. Leigh is affiliated with the University of Sussex, UK, and Winterton is affiliated with the University of Liverpool, UK. The book is distributed in the US by Springer Verlag.
