Synthesis of New Bisbenzimidazole Salts and Determination Their Ligand Activities in C-C Coupling Reactions

Abstract

New bisbenzimidazole salts were synthesized with 1,4-bis(1H-benzo[d]imidazol-1-yl)butane and benzyl halides. These new ligands carried out in Suzuki-Miyaura and Heck-Mizoroki C-C coupling reaction in the presence of palladium(II) acetate. It was observed that remarkable ligand activities of these benzimidazolium halides (L1, L2, L3).
