Initial studies have shown that aryl benzyl selenoxides are effective catalysts for the epoxidation of organic substrates. In the epoxidation of cis-cyclooctene, electron-withdrawing substituents in the selenoxides accelerate reaction while electron-donating substituents slow reaction. Benzyl 3,5-bistrifluoromethylphenyl selenoxide has proven to be the most effective catalyst. Initial studies with cyclic chalcogenoxides having an optically active binaphthyl skeleton as catalysts for the epoxidation and bromination of organic substrates will be discussed.
