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.
