Abstract
Tetra-n-butylammonium salts of transition metal-substituted heteropolytungstates, PW11MO n−39 , catalyze the epoxidation of stilbenes by t-butyl hydroperoxide (M=CoII, MnII, CuII, TiIV, RuIV, VV, NbV) and hydrogen peroxide (M=ZrIV) in acetonitrile. Epoxidation of cis-stilbene is non-stereospecific.
