Book Description
In diesem Buch werden wertvolle Informationen zur Chemie der Tragerreagenzien dargeboten, die bisher in der chemischen Literatur oder in entsprechenden Abstracts nur sehr schwer zu finden waren. Materialien und deren Praparation, sowie Analysemethoden und Fallstudien werden ausfuhrlich beschrieben. In der Entwicklung von Tragerreagenzien und deren potentieller Anwendung in der organischen Synthese gab es in jungster Zeit einen regelrechten Boom. Ein ganz entscheidender Vorteil von Tragerreagenzien ist ihre Umweltvertraglichkeit. Sie stellen somit eine interessante Alternative zu den konventionellen Reagenzien dar, die korrodierend, unwirtschaftlich und vor allem schwer zu entsorgen sind.

Book Description
Waste minimisation has a number of aims which include enhancing the intrinsic selectivity of any given process, providing a means of recovering reagents in a form which allows easy regeneration and the replacement of stoichiometric processes with catalytic ones. Solids, as catalysts or as supports for other reagents, offer potential for benefit in all these areas. This monograph provides an overview of the properties of the more useful solid catalysts and supported reagents, and highlights their most valuable applications in the preparation of organic chemicals in liquid phase reactions. Clean Synthesis Using Porous Inorganic Solid Catalysts and Supported Reagents is concerned with the use of solid catalysts in the clean synthesis of organic chemicals. The emphasis is on chemical processes of importance to the manufacture/preparation of fine and speciality chemicals, chemical intermediates and pharmaceutical intermediates, especially where catalysis is not currently used or where current catalysts are homogeneous, leading to difficult separation procedures and unacceptable levels of waste. This book focuses on solid catalysts based on inorganic supports and covers the emerging area of chemically modified mesoporous solid catalysts.

Book Description
Preparative Chemistry Using Supported Reagents explains a certain dimension in the methodology of organic reactions. This book discusses the physical methods for study that characterizes surfaces and their adsorbates and chemical reactivity at interfaces. The polymer-supported reagents, shape-selectivity within zeolites, and graphite intercalates are also described. Other topics include the metal oxides and their physico-chemical properties in catalysis and synthesis; photochemistry of adsorbed molecules; and magnetic spin resonance methods and applications to oxide surfaces. The physico-chemical characterization of supported reagents; polymer-supported oxidations; and alumina and alumina-supported reagents are likewise deliberated. This text also covers the novel aluminophosphate-based molecular sieves, clay-activated isomerization reactions, anionic activation, and cationic reactions. This publication is beneficial to chemists and researchers conducting work on supported reagents.

Book Description
The need to improve both the efficiency and environmental acceptability of industrial processes is driving the development of heterogeneous catalysts across the chemical industry, including commodity, specialty and fine chemicals and in pharmaceuticals and agrochemicals. Drawing on international research, Supported Catalysts and their Applications discusses aspects of the design, synthesis and application of solid supported reagents and catalysts, including supported reagents for multi-step organic synthesis; selectivity in oxidation catalysis; mesoporous molecular sieve catalysts; and the use of Zeolite Beta in organic reactions. In addition, the two discrete areas of heterogeneous catalysis (inorganic oxide materials and polymer-based catalysts) that were developing in parallel are now shown to be converging, which will be of great benefit to the whole field. Providing a snapshot of the state-of-the-art in this fast-moving field, this book will be welcomed by industrialists and researchers, particularly in the agrochemicals and pharmaceuticals industries.

Book Description
Chromic acid and chromium oxide are the two versatile Cr(VI) oxidants known to organic chemists for decades. The introduction of the Core's reagent , viz: pyridinium chlorochromate, in 1975 followed by the publications on several Cr(VI) oxidizing agents containing the -onium chromates and halochromates in the last three decades have very much changed the chemistry of oxidations with Chromium VI. Several of these new reagents have been shown to be mild so that they can be handled easily and the reacton products may also be controlled. Some of them are highly selective oxidants for positions like allylic hydroxylic group, etc., and some other are highly regioselective. The information on more than 36 such reagents reported in various internationally reputed journals spanning about 280 references have been collected and provided in this book in such a manner that it will be very useful for professionals, researchers, teachers and graduate students working in organic synthesis.
