Abstract: Ru(II) complexes bearing pyridyl-based benzimidazolyl-imidazolinyl tridentate NNN ligands were synthesized and structurally characterized. Their molecular structure was confirmed by X-ray crystallography. These complexes demonstrated good to excellent catalytic activity in the asymmetric transfer hydrogenation of ketones at room temperature, achieving up to 99% yields and 97% ee values.
