摘要:
New amino acidato complexes of Pd-II of stoichiometry [Pd(C-N)(Aa)](C-N = C,N-cyclometallated ligand, Aa = N,O-amino acidato ligand) have been obtained by reaction of [Pd(C-N)(acac)] (C-N = N,N-dimethylbenzylamine-C-2,N (dmba) (1) or N,N-dimethyl(S-alpha-phenylethyl)amine-C-2,N (S-dmphea) (2)) with glycine, chiral amino acids (alanine, phenylalanine and valine), and amino acid derivatives (N-acetylglycine and N-acetyl-alpha,beta-dehydroalanine) in MeOH. The compounds are characterized by IR, H-1 and C-13 NMR. The geometry of these complexes has been unambiguously determined by NOE difference experiments and NOESY measurements.
