Synthesis and catalytic activities of bimetallic Ru (II) arene complexes bearing bis-benzimidazoles

Öz

In this study, bis-benzimidazole ligands (1a-d) were synthesized using linker groups and they were evaluated as catalyst generated in situ from [RuCl₂(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 ¹H- and ¹³C-NMR, elemental analysis and IR spectroscopy. The catalytic activities of complexes having different chain lengths and Y (CH₃ or H) groups were compared. The highest conversion (99%) was obtained with 2b.
