摘要

研究了金（III）配合物\({\text{AuCl}}_{4}^{ - }\)、Au(bipy)Cl \(_{2}^{ + }\)、Au(en) \(_{2}^{{3 + }}\)和Au(C9H19N4)2+在pH为2.0和7.4的水溶液中与蛋氨酸（HMet）的反应；I = 0.2 M (NaCl), CAu = (5-10) × 10-5 mol/L, CHMet ＆lt；（6-50） × 10-5 mol/L)，温度25℃。蛋氨酸将金（III）还原为金(I)，但反应进行得比硫醇慢得多（慢了数百倍）。随着金（III）配合物中配体密度的增加，与HMet的反应速率显著降低。

On the Reaction of Gold(III) Complexes with Methionine

The reactions of gold(III) complexes \({\text{AuCl}}_{4}^{ - }\), Au(bipy)Cl\(_{2}^{ + }\), Au(en)\(_{2}^{{3 + }}\), and Au(C₉H₁₉N₄)²⁺ with methionine (HMet) were studied in aqueous solutions (pH 2.0 and 7.4; I = 0.2 M (NaCl), C_Au = (5–10) × 10^–5 mol/L, C_HMet < (6–50) × 10^–5 mol/L) at 25°C. Methionine reduces gold(III) to gold(I), but the reactions proceed much more slowly (by hundreds of times) than under the action of thiols. The rate of reactions with HMet markedly decreases with increasing denticity of ligands in the gold(III) complex.
