Abstract

Abstract A divanadium-substituted phosphotungstate,[γ-PW 10 O 38 V 2 (μ-OH) 2] 3−(I), showed the highest catalytic activity for the H 2 O 2-based epoxidation of allyl acetate among vanadium and tungsten complexes with a turnover number of 210. In the presence of I, various kinds of electron-deficient alkenes with acetate, ether, carbonyl, and chloro groups at the allylic positions could chemoselectively be oxidized to the corresponding epoxides ...
