摘要：

The complex [Ru-III(Me(3)tacn)(OH2)(2)(CF3CO2)](CF3CO2)(2) (Me(3)tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane, CF3CO2 = trifluoroacetate) is an effective catalyst for the oxidation of organic substrates by tert-butylhydroperoxide. It exhibits high activity and selectivity for alkene epoxidation under mild conditions. A heterolytic O-O cleavage mechanism and an alkylperoxoruthenium(VI) active intermediate are suggested for the catalytic alkene epoxidation.
