摘要：

The first efficient example of NHC-palladium pincer complex catalyzed aqueous Heck reaction with extremely low catalyst loading was realized without obvious hydrolysis of products by using a robust hydrophilic pyridine-bridged bisbenzimidazolylidene-palladium complex as a molecular catalyst, which tolerated various electronic properties of substituted functional groups in arenes.
