Abstract: A number of novel benzimidazole derivatives 14 were synthesized and the catalytic activity of these compounds in a catalytic system consisting of a benzimidazolium salt/Pd(OAc)2/K2CO3 were investigated in the Suzuki-Miyaura and Ullmann type homocoupling reactions under microwave irradiation. We obtained both cross coupling and homocoupling products of pyridine and some side products such as dimethylaminopyridine and unsubstituted pyridine.
Keywords: Suzuki-Miyaura reaction; homocoupling; N-heterocyclic carbene; microwave; pyridine derivatives
