摘要: A tandem chemoselective synthesis of 2-arylbenzofurans was accomplished from o-hydroxy-gem-(dibromovinyl)benzenes and BiAr3 reagents under palladium-catalyzed conditions. This unique synthetically valuable strategy proceeds through three consecutive coupling reactions involving triarylbismuth provides 2-arylbenzofuran products in high yields.
