Handbook of Metathesis – Catalyst Development and Mechanism 2e

RH Grubbs

The second edition of the "go-to" reference in this field is completely updated and features more than 80% new content, with emphasis on new developments in the field, especially in industrial applications. No other book covers the topic in such a comprehensive manner and in such high quality. Edited by the Nobel laureate R. H. Grubbs and A. G. Wenzel, this volume 1 of the 3-volume work focusses on catalyst development and mechanism. With a list of contributors that reads like a "Who's-Who" of metathesis, this is an indispensable one-stop reference for chemists in academia and industry. Other available volumes: Volume 2: Applications in Organic Synthesis, Editors: R. H. Grubbs and D. J. O¿Leary Volume 3: Polymer Synthesis, Editors: R. H. Grubbs and E. Khosravi

Robert H. Grubbs received his Ph.D. from Columbia University for work with Ron Breslow. After a postdoctoral year with Jim Collman at Stanford University, he joined the faculty at Michigan State University. In 1978, he moved to the California Institute of Technology, where he is now the Victor and Elizabeth Atkins Professor of Chemistry. Among many other awards, he received the Nobel Prize in 2005 for his research on the metathesis reaction. His research interests include polymer chemistry, organometallic catalysis, and the development of new synthetic organic methodology.

Anna G. Wenzel received her PhD at Harvard University under the guidance of Prof. E. N. Jacobsen. From 2003 to 2006, she joined the group of Prof. R. H. Grubbs as an NIH Postdoctoral Scholar. In 2006, she joined the faculty as an Assistant Professor at the W. M. Keck Science Department in Claremont, California. In 2012, she was promoted to Associate Professor. Her research topics are asymmetric catalysis, organometallic chemistry, and organic synthesis.
