imine ligands derivedfrom various N-(2-aminophenyl)benzenesulfonamides and NaBH4. Then, a series of N-coordinate Ru(II) arene complexes 7–12 were prepared from the reaction of [RuCl2(p-cymene)]2 with 1–6. The synthesized compounds were characterized by different methods such as NMR, FT-IR, and elemental analysis. 7–12 were used as catalysts for the transfer hydrogenation (TH) of ketones. At the same
