【 摘 要 】

A number of novel benzimidazolium salts having aryl substituents such as N-phenyl, 4-chlorophenyl and various alkyl substituents were synthesized. Their microwave-assisted catalytic activities were evaluated in Heck-Mizoroki and Suzuki-Miyaura cross-coupling reactions using a catalytic system consisting of Pd(OAc)₂/K₂CO₃ in DMF/H₂O under mild reaction conditions with consistent high yields, except those of 2-bromopyridine.
