2,2,2-trifluoroacetophenone is an efficient organocatalyst for a cheap, mild, fast, and environmentally friendly epoxidation of alkenes. Various olefins, mono-, di-, and trisubstituted, are epoxidized chemoselectively in high to quantitative yields utilizing low catalyst loadings and H2O2 as a green oxidant.
