Benzeneselenenic anhydride

A method for the conversion of alkenes to a-phenylseleno carbonyl conqmunds involves the use of benzeneselenenic anhydride. This reagent, which has a relatively short lifetime, is prepared in situ from diphenyl diselenide and r-butyl hydroperoxide. The alkene is converted to a phmylseleniranium ion... [Pg.522]
