Temperature effect on the epoxidation of olefins by an iron(III) porphyrin complex and tert-alkyl hydroperoxides

Abstract

An electron-deficient iron porphyrin complex catalyzes the epoxidation of olefins by tert-alkyl hydroperoxides via radical-free oxidation reactions in aprotic solvent; the epoxidation reactions were markedly influenced by reaction temperature and high yields of epoxide products were obtained with retention of stereospecificity at low temperature.
