Copper-catalyzed Hiyama cross-coupling using vinylsilanes and benzylic electrophiles†
Abstract
Allylbenzene derivatives are ubiquitous frameworks in organic chemistry. Herein is described an efficient copper-catalyzed cross-coupling reaction using vinylsilanes and benzyl bromides, leading to the synthesis of allylbenzenes. This methodology allows the use of cis, trans and 1,1′-disubstituted vinylsilanes as well as a large number of sensitive moieties.
