The reactions of MHCl(CO)(PPh3)3 with salts of α-amino acids give the hydrido-N,O-chelate complexes MH(CO)(NH2CHRCOO)(PPh3)2 (1a-g; M = Ru, Os).Complexes 1a-c can alternatively be prepared by oxidative addition of the appropriate α-amino acid to Ru(CO)3(PPh3)2.The crystal structure of 1b has been determined by an X-ray structural analysis.The leucinato compound 1c is an effective catalyst for the decomposition of formic acid.In contrast, reactions of RuHCl(CO)(PPh3)3 with α-amino acids afford the chloro-N,O-chelate complexes RuCl(CO)(NH2CHRCOO)(PPh3)2 2a-h.The decomposition reactions of 2c, 2g and 2h have been investigated. - Key Words: Ruthenium complexes / Osmium complex / Hydrido complexes / α-Amino acids / Oxidative Addition
