Anti-Markovnikov hydrophosphoroselenoylation of alkenes using phosphorodiselenoic acid esters leading to the formation of phosphonoselenoic acid esters

Phosphorodiselenoic acid esters with a binaphthyl group were reacted with alkenes in the presence of Bu3SnH and AIBN to give phosphonoselenoic acid esters in moderate to good yields. The addition of a phosphoroselenoyl group to alkenes proceeded in an anti-Markovnikov fashion. The diastereoselectivity was improved by the introduction of substituents to 3,3′-positions of a binaphthyl group.
