Abstract The catalytic activity of autoxidized copper (I) in the oxidation of para-disubstituted benzoins in dimethylsulfoxide by O 2 was studied both kinetically and by product analysis. Stoichiometry (1), accounts for more than 80% of the reaction. The catlytic oxydation was followed by monitering th consumption of O 2 manometrically by a fully automatic apparatus.
