The oxidation of diphenyl diselenide with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) represents a convenient mild method to produce a strongly electrophilic phenylselenium reagent. Clean phenylseleno methoxylations and hydroxylations of alkenes containing different types of functional groups can be effected by working in methanol or in acetonitrile and water, respectively. This new electrophilic reagent can also be employed to promote efficient cyclization reactions of alkenols to tetrahydrofurans or of alkenoic acids to lactones.
