Abstract
CoBr2 (5 mol %) in the presence of 2,2'-bipyridyl (5 mol %) enables electrophilic alkenylations between easily accessible alkenyl acetates or tosylates and various functionalized aryl zinc pivalates at ambient temperature. This cobalt-catalyzed process was further applicable to alkenyl zinc pivalates to provide substituted 1,3-dienes.Entities:
