Abstract:
Six novel tetrakis(N-benzimidazoliummethyl)benzene salts were synthesized using 1,2,4,5-tetrakis-(bromomethyl)benzene with 1-alkylbenzimidazole. The structures of all isolated compounds were elucidated based on spectroscopic methods (1H and 13C NMR, and FT-IR spectroscopy) and were investigated for their catalytic activities in the direct arylation of 2-n-propylthiazole, 2-n-buthyltiophene, 2-n-butylfuran, and 4,5-dimethylthiazole. All synthesized salts showed high catalytic activity for direct arylation of heteroaromatic compounds. ©AUTHOR(S)
