Abstract The transformation of olefins 1 into allylic ethers and alcohols 2 (R [dbnd] Me or H) was performed in 70–90% yields, using a catalytic amount of diphenyl diselenide, by an electrochemical oxyselenenylation-deselenenylation sequence. The electrooxidation of diphenyl diselenide in methanol or aqueous acetonitrile generates selenenylating reagents (PhSeOMe or PhSeOH), which subsequently react with 1 to produce the corresponding ...
