The system comprised of manganese(II) acetate or sulfate, 1,4,7-trimethyl-1,4,7-triazacyclononane (TMTACN) and ascorbic acid efficiently catalyzes the epoxidation of olefins and the oxidation of alcohols with hydrogen peroxide. For example, in the presence of as little as 0.03 mol% of Mn 2÷, methyl
