Radical phosphinylation of α,α-diaryl allylic alcohols with concomitant 1,2-aryl migration

Abstract

A novel radical phosphinylation of α,α-diaryl allylic alcohols with arylphosphine oxides was described for the direct preparation of α-aryl-β-phosphinylated carbonyl ketones in medium to good yields via 1,2-aryl migration. In this reaction, formation of new C(Ar)-C(sp(3)) and C(sp(3))-P bonds was observed.
