Abstract

An NHC-palladium pincer complex catalyzes aqueous Heck reactions with extremely low catalyst loading without obvious hydrolysis of products. The robust hydrophilic pyridine-bridged bisbenzimidazolylidene-palladium complex, that is used as the molecular catalyst, allows the conversion of a broad range of aryl iodides.
