Book Description
"Recently, organometallic reactions in aqueous media have received considerable attention in organic synthesis because of environmental and economical concerns and synthetic efficiency. In this connection, the synthetic utility of environmentally benign non-toxic bismuth metal for aqueous organometallic reactions is investigated. Bismuth metal activated by ammonium hydrogen fluoride can efficiently reduce a wide variety of alpha-halocarbonyl compounds in aqueous media to provide the corresponding dehalogenated reduction products in excellent yields. Zinc fluoride is also found to be effective in activating bismuth to mediate the crossed aldol type reactions of diverse alpha-bromocarbonyl compounds with aldehydes in aqueous media to afford the corresponding beta-hydroxycarbonyl compounds in moderate to high yields. The scope of bismuth-mediated aqueous organometallic reactions is successfully extended to the Reformatsky type reactions. The factors that affect the reactivity of these reactions are examined and plausible reaction mechanisms are proposed." --

Biphasic Chemistry and The Solvent Case
Author: Jean-Philippe Goddard
Publisher: John Wiley & Sons
ISBN: 111969504X
Category : Science
Languages : en
Pages : 162
Book Description
Biphasic Chemistry and The Solvent Case examines recent improvements in reaction conditions, in order to affirm the role of chemistry in the sustainable field. This book shows that those who work within the chemistry industry support limits for the use of toxic or flammable solvents, since it reduces the purifications to simple filtrations. Thanks to commercial scavengers, solid phase syntheses are now available to all. Fluorine biphasic catalysis enables extremely efficient catalyst recycling and has a high applicability potential at the industrial level. This book also reviews the many studies that have shown that water is a solvent of choice for most synthetic reactions. Particular traits can be obtained and the effects on thermodynamics make it possible to operate at lower temperatures, thereby achieving energy savings. Finally the great diversity of application of the reactions without solvents is illustrated.

Organic Synthesis in Water
Author: P.A. Grieco
Publisher: Springer Science & Business Media
ISBN: 940114950X
Category : Science
Languages : en
Pages : 321
Book Description
The use of water as a medium for promoting organic reactions has been rather neglected in the development of organic synthesis, despite the fact that it is the solvent in which almost all biochemical processes take place. Chemists have only recently started to appreciate the enormous potential water has to offer in the development of new synthetic reactions and strategies, where it can offer benefits in both unique chemistry and reduced environmental impact. In this new book, the editor, well known for his contribution to the development of water as a useful medium in synthetic organic chemistry, has assembled an international team of authors, themselves at the forefront of research into the use of the unique properties of water carrying out organic transformations, to provide a timely and concise overview of current research. By focusing on the practical use of water in synthetic organic chemistry, and with the concern for the use of solvents in organic chemistry, professional chemists, particularly those involved in industrial research and development, will find this book an essential guide to the current state of the art, and a useful starting point in their own research. Academic chemists, including postgraduate and advanced undergraduate students, will find this book an invaluable guide to this exciting and important area of chemistry.
