Guanidines, amidines and phosphazenes have been attracting attention in organic synthesis due to their potential functionality resulting from their extremely strong basicity. They are also promising catalysts because of their potential for easy molecular modification, possible recyclability, and reduced or zero toxicity. Importantly, these molecules can be derived as natural products – valuable as scientists move towards “sustainable chemistry”, where reagents and catalysts are derived from biomaterial sources. Superbases for Organic Synthesis is an essential guide to these important molecules for preparative organic synthesis. Topics covered include the following aspects: an introduction to organosuperbases physicochemical properties of organic superbases amidines and guanidines in organic synthesis phosphazene: preparation, reaction and catalytic role polymer-supported organosuperbases application of organosuperbases to total synthesis related organocatalysts: proton sponges and urea derivatives amidines and guanidines in natural products and medicines Superbases for Organic Synthesis is a comprehensive, authoritative and up-to-date guide to these important reagents for organic chemists, drug discovery researchers and those interested in the chemistry of natural products.

Lewis Base Catalysis In Organic Synthesis

This three-volume set represents the first comprehensive coverage of the rapidly expanding field of Lewis base catalysis that has attracted enormous attention in recent years. Lewis base catalysis is a conceptually novel paradigm that encompasses an extremely wide variety of preparatively useful transformations and is particularly effective for enantioselectively constructing new stereogenic centers. As electron-pair donors, Lewis bases can influence the rate and stereochemical course of myriad synthetic organic reactions. The book presents the conceptual/mechanistic principles that underlie Lewis base catalysis, and then builds upon that foundation with a thorough presentation of many different reaction types. And last but not least, the editors, Prof. Edwin Vedejs and Prof. Scott E. Denmark, are without doubt the leaders in this emerging field and have compiled high quality contributions from an impressive collection of international experts.

Main Group Metal Organometallics In Organic Synthesis

Author : Edward W. Abel
ISBN : 0080423183
Genre : Science

The individual chapters in this volume cover the scope and impact of main group organometallic compounds and reagents on organic synthesis during the last ten to fifteen years. In a number of chapters, topics are dealt with in detail that either were not covered at all in COMC (eg selenium, tellurium) or were given scant attention (eg oxymercuration, organoantimony compounds). Certain topics, like directed metallation and LiKOR bases have only achieved prominence in synthesis in the last ten years, and are now reviewed by leading experts.

Handbook of Reagents for Organic Synthesis Acidic and Basic Reagents Hans J. Reich University of Wisconsin at Madison, USA James H. Rigby Wayne State University, Detroit, 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. Handbook of Reagents for Organic Synthesis: Acidic and Basic Reagents, presents a selection of articles on the most fundamental and versatile reagents for effecting organic transformations that were originally included in EROS. In selecting candidate entries for inclusion in this particular collection, the editors adopted a broad set of criteria for defining what exactly constitutes an acidic or basic reagent. Each article contains all of the information found in EROS as well as expanded related reagents listings. Additional 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 thorough and comprehensive handbook will prove of widespread appeal.

Concise Encyclopedia Of The Chemical Properties Of Materials

This Concise Encyclopedia draws its material from the award-winning Encyclopedia of Materials: Science and Technology, and includes updates and revisions not available in the original set. The chemical properties discussed in EMSAT which have selected for this volume include Production and Refining processes (principally for metallic materials, but also the processes of polymerization), the thermodynamics and kinetics of phase equilibria, electrochemical reactions and gas-solid reactions. An extremely important example of the latter process is oxidation and corrosion, and a majority of the articles included are concerned with the kinetics, thermodynamics and mechanisms of corrosion (including stress corrosion) in metallic systems. Articles on protection against corrosion have also been included. The chemical behaviour of a range of materials is covered, often specifically with reference to metals and alloys, although there are also examples relating to polymers and non-oxide ceramics. Two articles on chemically modified wood have also been included. The whole assembly provides the reader with an up-to-date understanding of the chemical properties of a wide range of materials of engineering importance. The majority of contributions contain quantitative data, the others are predominantly descriptive in nature where it is more appropriate for the type of material in question. This Concise Encyclopedia will be useful to faculty and postgraduate research students in materials science and technology and related disciplines, especially physics, chemistry, engineering and biomedical science; as well as researchers and staff in government and industry.
