Abstract

Epoxidation of styrene with m-CPBA in the presence of Mn(TPFPP)Cl was improved to high yield (98–100%) and excellent selectivity (100%) by using n-Bu4NOAc or n-Bu4NBr as co-catalysts in less than 5 min. Also comparison of co-catalytic activity of n-Bu4NOAc, n-Bu4NBr and imidazole in epoxidation of cis-stilbene and styrene was carried out at similar conditions.
