Selective Epoxidation of Styrene with Mn-TAML/TBHP

Abstract:

Styrene was selectively oxidized to styrene oxide with macrocylic amido Mn (II) complex as catalyst and tert-Butyl hydroperoxide (TBHP) as oxidant. The effects of reaction temperature, reaction time, solvents, amount of catalyst and oxidant on the conversion and selectivity of styrene epoxidation were investigated. The optimized conditions were achieved by molar ratio of n (catalyst) :n (styrene)=1% in acetonitrile solvent at 75 °C in 1.5 h. Under optimum reaction conditions, reaction conversion of 92.6% and selectivity of 86.9 % were obtained.
