abstract={Catalysis of oxidation of aminothiols by copper ions was studied depending on the structure of aminothiols and pH of the medium. The catalytic reaction proceeds in the inner coordination sphere of Cu+. At pH 7-9, oxidation of bidentate aminothiols involves reduction of O2 to H 2O2. At pH 9-13, oxidation of chelating aminothiols is accompanied by reduction of O2 to H2O, whereas oxidation of weak-chelating aminothiols still proceeds by the former mechanism. In this process, the thiolate anions coordinated to the Cu+ ions lose one electron each and are oxidized to amino disulfides, which go from the inner sphere of the Cu+ complex into a solution. Procedures developed for the determination of amino disulfides, the chemiluminescence determination of H2O2 in the presence of aminothiols as luminescence quenchers, and a modified polarographic procedure for the determination of O2 allowed us to establish that oxidation of aminothiols is not accompanied by catalytic decomposition of H2O2 that formed.},
