Özet
Abstract The reaction of 1‐alkylbenzimidazole derivatives with o ‐/ p ‐di(chloromethyl)benzene results in the formation of the new o ‐/ p ‐xylyl‐linked bis(benzimidazolium) salts, 1 and 2, respectively. The salts were characterized by NMR spectroscopy and elemental analysis. The in situ prepared complexes derived from Pd(OAc) 2 –1 and 2 exhibit catalytic activity (61–98%), to give the Heck coupling products of aryl bromides and styrene.
