Use of bis(benzimidazolium) - palladium system as a convenient catalyst for Heck and Suzuki coupling reactions of aryl bromides and chlorides

WOS: 000236916700003Six new, sterically demanding bis(benzimidazolium) salts (2a-f) as NHC precursors have been synthesized and characterized. These salts, in combination with palladium acetate, provide active catalysts for the cross-coupling of aryl chlorides and bromides under mild conditions in aqueous media.
