A divanadium‐substituted phosphotungstate [γ‐PW 10 O 38 V 2 (μ‐OH) 2 ] 3− has been used as a catalyst in the chemoselective oxidation of various kinds of electron‐deficient alkenes, with acetate, ether, carbonyl, and chloro groups at the allylic positions, to give the corresponding epoxides in high yields with only an equimolar amount of H 2 O 2 . Even acrylonitrile and methacrylonitrile could be epoxidized without formation of the corresponding amides. For more information see the Full Paper by N. Mizuno et al. on page 7549 ff.
