A reação de metátese de olefinas: reorganização e ciclização de compostos orgânicos

Abstract

Recebido em 12/7/04; aceito em 13/10/04; publicado na web em 4/2/05 THE OLEFIN METATHESIS REACTION: REORGANIZATION AND CICLIZATION OF ORGANIC COMPOUNDS. The olefin metathesis reaction allows the exchange of complex alkyl units between two olefins, with the formation of a new olefinic link and a sub-product olefin usually ethylene. This reaction has found extensive application in the last ten years with the development of the Grubbs and Schrock catalysts, in total synthesis of complex organic molecules, as opposed to the very important use in the petrochemical industry with relatively simple molecules. This review intends to trace a historical and mechanistic pathway from industry to academy, before illustrating the more recent advances.
