Resumo

Methyl oleate can be efficiently (yield and selectivity attain 100%, turnover number is up to 2000) epoxidized with hydrogen peroxide in acetonitrile solution at 25 degrees C using the combination "[Mn2L2O3](PF6)(2) (L= 1,4,7-trimethyl-1,4,7-triazacyclononane)/oxalic acid" as a catalyst. Kinetic features of the reaction were studied and the conclusion has been made that high-valent oxo-manganese rather than hydroxyl radicals is a crucial oxidizing species in this process.
