Substitution versus redox reactions of gold(iii) complexes with l-cysteine, l-methionine and glutathione

The reactions of [AuCl₄]⁻, [Au(terpy)Cl]²⁺, [Au(bpma)Cl]²⁺ and [Au(dien)Cl]²⁺ with l-cysteine, l-methionine and glutathione were examined using stopped-flow, cyclovoltammetry, ¹H NMR and ESI-MS techniques.
