摘要：
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 d(8) ions in the direction of the reaction was found.
