## Abstract A mixture of novel benzimidazole salts (2a–f), Pd(OAc)~2~ and K~2~CO~3~ in DMFH~2~O catalyzes, in high yield, the Heck cross‐coupling reaction assisted by microwave irradiation in a short time. All synthesized novel benzimidazole derivatives were characterized by elemental analysis and
## Abstract The use of palladium catalyst systems including novel benzimidazole salts (I) gives better yields and very short reaction times compared with those given in the literature.
A mixture of benzimidazole salts (2-7), Pd(OAc) 2 and K 2 CO 3 in DMF-H 2 O catalyzes the Suzuki-Miyaura cross-coupling reactions promoted by microwave irradiation resulting in high yield within a short time. In particular, the yield of the Suzuki-Miyaura reactions with aryl bromides was found to be
