A study has been made of the oxidation of disulphides of different structure by hydrogen peroxide in the presence of nitrosubstituted phthalocyanines of transition metals. It has been established that phthalocyanines in a homophase system ensure a higher initial oxidation rate of disulphides to disulphones and thiosulphonates than Na2WO4 in a two-phase system with the use of interphase transfer catalysts.
