Metal Complexes of Biological Important Ligands. LXXXII. Triphenylphosphine Molybdenum, Tungsten, Ruthenium, and Iridium Complexes of N-Acyl-α-AminocarboxylatesThe reactions of the hydrido complexes RuHCl(CO) · (PPh3)3, RuH2(PPh3)4 and IrH3(PPh3)3 with N-acyl-α-aminocarboxylates give the carboxylate complexes RuCl(O2CCHRNHCOR′)(CO)(PPh3)2 (1-3), RuH(O2CCHRNHCOR′)(PPh3)3 (4-6) and IrH2(O2CCH2NHCOPh)(PPh3)3 (7). The structure of RuCl · (O2CCHNHCOPh)(CO)(PPh3)2 (1) has been determined by x-ray diffraction. The triphenylphosphine complexes MBr · (O2CCH2NHCOR)(CO)2(PPh3)2 (M = Mo, W) (8-12) and Mo(O2CCHRNHCOR′)2(CO)2(PPh3)2 (13-17) are formed from MBr2(CO)2(PPh3)2 (M = Mo, W) with one or two equivalents of N-acyl-a-aminoacidates, respectively.
Notes:
Die Hydrido-Komplexe RuHCl(CO)(PPh3)3, RuH2(PPh3)4 und IrH3(PPh3)3 reagieren mit N-Acyl-α-Amino-carbonsäuren unter Bildung der Carboxylat-Komplexe RuCl(O2CCHRNHCOR′)(CO)(PPh3)2 (1-3), RuH(O2CCHRNHCOR′)(PPh3)3 (4-6) und IrH2(O2CCH2NHCOPh)(PPh3)3 (7). Die Struktur von RuCl(O2CCH2NHCOPh)(CO)(PPh3)2 (1) wurde röntgenographisch bestimmt. Phosphan-Komplexe der Formel MBr(O2CCH2NHCOR)(CO)2(PPh3)2 (M = Mo, W) (8-12) und Mo(O2CCHRNHCOR′)2(CO)2(PPh3)2 (13-17) entstehen bei der Umsetzung von MBr2(CO)2(PPh3)2 mit einem bzw. zwei Äquivalenten N-Acyl-α-Aminocarboxylat-Anionen.
