Catalytic activity of a series of copper(I) complexes containing dihydrobis(2-mercapto-benzimidazolyl) borate (Bb), and phosphine co-ligands was investigated in the synthesis of N-heterocycle compounds including 2H-indazoles and 5-substituted 1H-tetrazoles. The copper(I) complex containing tricyclohexylphosphine co-ligand, [Cu(Bb)(PCy3)], displayed the highest catalytic activities for the formation of 2H-indazoles and 1H-tetrazoles. Apart from the nontoxicity and strong σ-donating ability of the introduced ligands, the introduced catalyst required easy handling processes. The catalytic reactions were successfully performed at low catalyst loadings in either PEG-200 or DMF and in relatively short reaction times. The diversity of these reactions was also explored with 20 and 12 examples. Finally, the above reported catalytic system was amenable to large-scale production of these N-heterocycle compounds
