Platinum(IV) Complexes with α-Amino Acid Esters and Peptide Esters; 13N and 195Pt NMR Spectra of Platinum Complexes with α-Amino Acids

Abstract

The platinum(IV) complexes PtX4L2 (X = Cl, Br; 2 X = oxalate; L = glyOEt, glyglyOEt, gly-cleuOEt; 2 L = metOEt) have been obtained by oxidative addition of halogenes to platinum(II) compounds PtX2L2. A high field shift of δ15N ( ∼ 50 ppm) is observed for the coordinated amino acid ligand of various platinum complexes, compared to the free ligand. Platinum(II) and platinum(IV) can be distinguished by their 195Pt NMR signals.
