Palladium(0)‐Catalyzed Cross‐Coupling of 1,1‐Diboronates with Vinyl Bromides and 1,1‐Dibromoalkenes

Abstract

Palladium-catalyzed cross-coupling reactions of 1,1-diboronates with vinyl bromides and dibromoalkenes were found to afford 1,4-dienes and allenes, respectively. These reactions utilize the high reactivities of both 1,1-diboronates and allylboron intermediates generated in the initial coupling.
