Abstract
cis-PtX2L2 (X = Cl, Br, I; L = alpha -amino acid ester, peptide ester) and cis-PtZL2 (H2Z = oxalic acid, malonic acid) were prepd. from PtX42- or PtZ22- and L. The dipeptide complexes were also prepd. via peptide synthesis from PtCl2(NH2CHRCO2H)2 and alpha -amino acid esters using carbodiimide as the coupling agent. PtCl2L2 (L = alpha -amino acid ester) were prepd. from cis-Pt(NH2CHRCO)2 and alc. ...
