Abstract The interaction of Pt(II) and Au(III) with disulfides (l-cystine, cystamine, dl-homocystine and 3,3′-dithiodipropionic acid) in hydrochloric acid aqueous solutions was studied. In the case of Pt(II), the oxidative addition reaction leads to formation of the Pt(IV) thiol complex. In the case of Au(III) disulfide, binding causes a reduction to Au(0) and oxidation of the disulfide to sulfonic acid. Cyclic voltammetry and different spectroscopic methods were used to study the process. The pattern of influence of the metallic properties for d8 ions in the direction of the reaction was found.

Pt(II)和Au(III)与有机二硫化物在盐酸水溶液中的相互作用

摘要 研究了 Pt(II) 和 Au(III) 与二硫化物（l-胱氨酸、胱胺、dl-高胱氨酸和 3,3'-二硫代二丙酸）在盐酸水溶液中的相互作用。在 Pt(II) 的情况下，氧化加成反应导致形成 Pt(IV) 硫醇复合物。在 Au(III) 二硫化物的情况下，结合导致 Au(0) 还原和二硫化物氧化成磺酸。循环伏安法和不同的光谱方法被用来研究这个过程。发现了 d8 离子在反应方向上的金属性质的影响模式。
