Polymers are huge macromolecules composed of repeating structural units. While polymer in popular usage suggests plastic, the term actually refers to a large class of natural and synthetic materials. Due to the extraordinary range of properties accessible, polymers have come to play an essential and ubiquitous role in everyday life - from plastics and elastomers on the one hand to natural biopolymers such as DNA and proteins on the other hand. The study of polymer science begins with understanding the methods in which these materials are synthesized. Polymer synthesis is a complex procedure and can take place in a variety of ways. This book brings together the "Who is who" of polymer science to give the readers an overview of the large field of polymer synthesis. It is a one-stop reference and a must-have for all Chemists, Polymer Chemists, Chemists in Industry, and Materials Scientists.

Handbook of Reagents for Organic Synthesis Reagents, Auxiliaries and Catalysts for C-C Bond Formation Robert M. Coates and Scott E. Denmark The University of Illinois, Urbana, USA Recognising the critical need for bringing a handy reference work that deals with the most popular reagents in synthesis to the laboratory of practising organic chemists, the Editors, of the acclaimed Encyclopedia of Reagents for Organic Synthesis (EROS) have selected the most important and useful reagents employed in contemporary organic synthesis. The Handbook of Reagents for Organic Synthesis; Reagents Auxiliaries and Catalysts for C-C Bond Formation, provides practical and concise information on a diverse group of reagents. To familiarise the user with the spectrum of reagents contained within this volume, the editors have subdivided more than 200 entries into 22 classes based on their chemical structures and function. The articles, arranged alphabetically, contain all of the information found in EROS as well as expanded reagents listings. In addition, new listings of recently published review articles and monographs are included, as well as relevant Organic Syntheses procedures that deal with either the preparations or reactions of the featured reagents. This comprehensive and well referenced handbook will prove of great value to all practitioners in the field of organic chemistry.
Chiral Building Blocks in Asymmetric Synthesis A comprehensive introduction to the important classes of chiral building blocks Chirality — the asymmetric quality found in certain chemical compounds — plays an essential role in our world: chiral compounds can be found in biology, pharmaceutical compounds, agrochemicals, and fragrances. The stereoselective preparation of these complex molecular constructions constitutes a challenge. To this end, modern asymmetric synthesis utilizes a variety of valuable and efficient reagents employed as chiral auxiliaries, metal complexes and organocatalysts in stereoselective catalysis, and enantiopure reactants termed as chiral building blocks. In Chiral Building Blocks in Asymmetric Synthesis, the achievements in the fields of preparation of and applications of chiral blocks are presented. In doing so, the book comprehensively discusses the important classes of these reactants as the key for the asymmetric synthesis of chiral molecules. As such, it is an indispensable resource about synthetic methods, as well as possible modifications and transformations of important classes of chiral compounds. It also highlights the importance of their use as reactants and auxiliaries in the preparation of more sophisticated molecules or supramolecular systems. In Chiral Building Blocks in Asymmetric Synthesis readers will also find: Organization according to the most important compound classes — e.g. amino acids, BINOL and its derivatives, terpenes, and others — with an emphasis on synthesis and application A focus on the use of chiral building blocks for the preparation of bioactive compounds and supramolecular assemblies Chiral Building Blocks in Asymmetric Synthesis is a useful reference for organic chemists, catalytic chemists, chemists in industry, medicinal chemists, pharmaceutical chemists, and the libraries that support them.
The major emphasis here is on enantioselective reactions using asymmetric catalysts. Examples from the total synthesis of various natural and unnatural targets validates the utility of the synthetic methods. Specific topics discussed: cycloaddition, cycloisomerization and sigmatropic rearrangement reactions, allylic and carbonyl functionalization reactions, metal-catalyzed cross-coupling reactions, desymmetrization, fluorination, polymerization and sulfide oxidation reactions. This volume is part of a 3-volume set: Science of Synthesis Stereoselective Synthesis Workbench Edition Further information about Stereoselective Synthesis (including sample pages and the table of contents)
Recently, the synthesis of neutral and cationic group(VI) imido/oxo alkylidene N-heterocyclic carbene (NHC) complexes that tolerate protic functional groups and aldehydes was reported. Unprecedented turnover numbers of up to 1.2 million were found for their silica-supported representatives. Some group(VI) alkylidene NHC complexes even display stability towards moisture and air. Coordination of the NHC to tungsten imido bistriflate precursor complexes, however, can lead to undesired side reactions. This work consequently aimed at the development of novel, more efficient routes to neutral and cationic tungsten imido/oxo alkylidene NHC complexes. In addition, some molybdenum imido alkylidene NHC complexes were targeted. Thereby, the scope of synthetically accessible complexes was broadened and, subsequently, their reactivity in ring-opening metathesis polymerization (ROMP) was probed. Those complexes were used as thermally latent initiators for the ROMP of dicyclopentadiene. Precise determination of the onset temperature of polymerization was achieved via monitoring with differential scanning calorimetry. Furthermore, the selectivity of novel complexes was tested for the formation of stereoregular polymers through ROMP of enantiomerically pure norbornene derivatives, which allowed for the synthesis of up to 98% trans-isotactic or cis-syndiotactic polymers depending on the steric demand of the imido and the alkoxide ligand.
The only comprehensive book covering of advances in metallabenzene chemistry—written by the leading experts in the field Metallabenzenes: An Expert View provides comprehensive coverage of all aspects of metallabenzene chemistry, including syntheses, reactions, physical properties, and theoretical treatments of metallabenzenes. Fused ring metallabenzenes, heterometallabenzenes, and metallabenzenes that are p-bound to other metal fragments are also discussed in depth. Although benzene itself was discovered in 1825, it wasn’t until 1982 that the first metallabenzene was isolated. Since then, interest in these compounds has built steadily, and metallabenzene chemistry is now a flourishing sub discipline in its own right. A diverse range of synthetic approaches to these compounds have been devised, and new developments and discoveries have appeared regularly over the past several decades. Yet, until now, no books devoted to this fascinating and important class of chemical compounds have been available to researchers and students. This bookfills that gap in the literature with a comprehensive review of recent advances in metallabenzene chemistry theory and applications. Featuring contributions by an international group of experts in the field, each chapter summarizes important recent research in and significant contributions to various aspects of metallabenzene chemistry. Provides academics, researchers and graduate students with a comprehensive review of advances in metallabenzene research Covers fused-ring metallabenzenes—including metallanaphthalenes, metallabenzofurans, and metallabenzothiophenes—as well as p-bound heterometallabenzenes and metallabenzenes Reviews the latest computational studies that have led to the theoretical understanding of metallabenzenes Includes critical discussions of metallabenzene aromaticity, an area rarely covered by computational experts Metallabenzenes: An Expert View is an important working resource for those working in organometallic chemistry, aromaticity, coordination chemistry, theoretical chemistry, catalysis and materials science. It is also an excellent text for graduate-level courses in those areas.
