Y. Masaki et al., TETRACYANOETHYLENE-HYDROGEN PEROXIDE, A MILD EPOXIDATION SYSTEM OF OLEFINS, Chemical and Pharmaceutical Bulletin, 43(4), 1995, pp. 686-688
A reagent combination system, tetracyanoethylene-30% hydrogen peroxide
, was found to epoxidize olefins efficiently in acetonitrile at room t
emperature in a stereospecific manner with retention of the configurat
ion of the double bond.
