Asymmetric transfer hydrogenation (ATH) of cyclic imines using [RuCl(η(6)-p-cymene)TsDPEN] (TsDPEN = N-tosyl-1,2-diphenylethylenediamine) was tested with various aliphatic (secondary, tertiary) and aromatic amines employed in the HCOOH-base hydrogen donor mixture. Significant differences in reaction rates and stereoselectivity were observed, which pointed

A series of 1,2,3-triazol-5-ylidene (tzNHC) complexes of a (p-cymene)ruthenium system was synthesized. The reactivity of the N-bonded and C-bonded aryl groups in the tzNHC ligand was found to be significantly different with respect to intramolecular aromatic C-H bond activation.
