Abstract

Abstract: Several cobalt(II) complexes supported by tetradentate aminobenzimidazole (N4) ligands and a tridentate nitrogen (N3) ligand have been prepared and characterized. X‐ray crystallographic analysis indicates that the cobalt complex of BPMB (BPMB=1, 2‐bis(( S )‐2‐(1‐methyl‐1H‐benzo[d]imidazol‐2‐yl) pyrrolidin‐1‐yl)ethane) ligand shows a distorted octahedral configuration. These cobalt(II) complexes can catalyze the transfer hydrogenation reaction of simple olefins with ammonia borane as a hydrogen source, and a variety of terminal olefins can be reduced to corresponding alkanes in good to excellent yields under mild reaction conditions. Note that Co−N3 complex provides an inferior outcome than those of Co−N4 complexes. Abstract :
