A number of Cu(II) complexes of peptide derivatives that coordinate via N-deprotonation at the C-terminal amino acid residue have been characterized by titrimetry and the Cu(III)-Cu(II) electrochemical potentials. Reaction of these complexes with persulfate induces oxidative decarboxylation and hydrolysis of the resulting N-acylimines to carboxamide and either HCHO, CH 3 CHO, or acetone depending on
已经通过滴定法和 Cu(III)-Cu(II) 电化学电位表征了许多肽衍生物的 Cu(II) 复合物,它们通过 C 端氨基酸残基的 N-去质子化进行了配位。这些复合物与过硫酸盐的反应会诱导产生的 N-酰基亚胺氧化脱羧和水解为甲酰胺和 HCHO、CH 3 CHO 或丙酮,具体取决于 C 末端残基的身份
