摘要：

A biphasic system consisting of 35% H2O2 and methyltrioxorhenium(VII)/pyrazole in CH2Cl2 catalyzes the epoxidation of a wide range of olefins in excellent yields. Both the reactivity and selectivity of the new catalytic surpasses all known MTO/Lewis base catalysts. The considerable ligand accelerating effect observed here is attributed to the stability of pyrazole against oxidation. (C) 1998 Elsevier Science S.A. All rights reserved.
