Abstract :In this study, bis-benzimidazole ligands ( 1a-d ) were synthesized using linker groups and they were evaluated as catalyst generated in situ from [RuCl 2 ( p -cymene)] 2 for transfer hydrogenation (TH) of acetophenone. The bimetallic Ru (II) arene complex ( 2b ) synthesized from ligand 1b which showed the best activity among the ligands in the catalytic TH reaction. The obtained ligands and 2b complex were characterized by 1 H- and 13 C-NMR, elemental analysis and IR spectroscopy. The catalytic activities of complexes having different chain lengths and Y (CH 3 or H) groups were compared. The highest conversion (99%) was obtained with 2b . 0000-0002-7422-6593Keywords : Bis-benzimidazole, ruthenium, transfer hydrogenation
