摘要

Abstract A tandem chemoselective synthesis of 2-arylbenzofurans was accomplished from o- hydroxy-gem-(dibromovinyl) benzenes and BiAr 3 reagents under palladium-catalyzed conditions. This unique and synthetically valuable strategy proceeds through three consecutive coupling reactions involving triarylbismuth reagents and provides 2- arylbenzofuran products in high yields.
