The complex trans,cis-[RuCl2(PPh3)2(ampi)] (2) was prepared by reaction of RuCl2(PPh3)3 with 2-aminomethylpiperidine(ampi) (1). [RuCl2(PPh2(CH2)nPPh2)(ampi) (n?=?3, 4, 5)] (35) were synthesized by displacement of two PPh3 with chelating phosphine ligands. All complexes (25) were characterized by 1?H, 13C, 31P NMR, IR and UV-visible spectroscopy and elemental analysis. They were found to be efficient catalysts for transfer hydrogen reactions.
