Concerted Organic and Bio-Organic Mechanisms: New Directions in Organic & Biological Chemistry

Autor Andrew Williams
en Limba Engleză Hardback – 27 oct 1999
The concept of concerted mechanisms was formulated nearly 90 years ago and virtually all general organic chemistry texts mention it. Until now, however, no monograph has addressed the concept explicitly. Over the last two decades, substantial advancements made in the development of precise methods for elucidating concerted mechanisms have heightened the need for a comprehensive text on the subject.
Concerted Organic and Bio-organic Mechanisms gathers the salient materials related to this emerging field into a single text. It sets forth the precise definition of concertedness-along with working sub-definitions-and describes rigorous experimental tools chemists can use to diagnose the existence or absence of concerted mechanisms.
Advances in our understanding of concerted mechanisms lead to further questions. Concerted Organic and Bio-organic Mechanisms provides the background and the tools researchers need to consider these important questions and further advance the frontiers of reactions, synthesis, and catalysis.

Recenzii

"This is an excellent and authoritative book that covers not only concerted reactions but also stepwise reactions originally posed to be concerted. The book is very densely written, with much information, and with a careful reasoning style that demands concentration from the reader…offers a concise guide to a wide range of mechanistic studies. It will reward the careful student or researcher."
--Charles L. Perrin, University of California, San Diego, American Chemical Society Journal

Descriere

This book presents an encyclopedic comparison of more than 7,000 commercially available enzymes, restriction endonucleases, DNA methyltransferases and enzyme mixtures, blends, and complexes. It lists the general and unique properties of each enzyme so readers can directly compare differences among products and offers a worldwide listing of nearly 100 enzyme suppliers. Designed for quick reference, it features a comprehensive user's guide includes and indexes by by both EC number and enzyme name, synonyms, and abbreviations.
