WebThe rate of epoxidation of an allylic alcohol with TBHP in the presence of a vanadium catalyst is more than 1000 times the rate of epoxidation of the parent alkene. 5 An increase in reaction rate has also been observed in the vanadium-catalyzed epoxidation of homoallylic and bishomoallylic alcohols due to the location of the hydroxy group. Hence …
