Written for chemists in industry and academia, this ready reference and handbook summarizes recent progress in the development of new catalysts that do not require precious metals. The research thus presented points the way to how new catalysts may ultimately supplant the use of precious metals in some types of reactions, while highlighting the remaining challenges.
An essential copanion for organic and catalytic chemists, as well as those working with/on organometallics and graduate students.

From the contents:

* Catalysis Involving the H' Transfer Reactions of First-Row Transition Metals

Dieses Handbuch für Chemiker in der Industrie und an Forschungsinstituten fasst die jüngsten Fortschritte auf dem Gebiet übersichtlich zusammen. Die einzelnen Beiträge zeigen, bei welchen Reaktionen neue Katalysatoren den Einsatz teurer Metalle überflüssig machen könnten, verschweigen aber auch nicht, welche Probleme dadurch noch nicht gelöst werden.

After 21 years at Brookhaven National Laboratory in Long Island, New York, Morris Bullock moved to Pacific Northwest National Laboratory in 2006, where he is a Laboratory Fellow, as well as Director of the Center for Molecular Electrocatalysis. Dr. Bullock's research interests focus on reactivity of metal hydrides, including proton transfer, hydride transfer, and hydrogen atom transfer reactions, and on the development of molecular catalysts for the oxidation of hydrogen and production of hydrogen.
