Silver-catalyzed carbonphosphonation of α,α-diaryl allylic alcohols: synthesis of β-aryl-γ-ketophosphonates

Abstract

Silver-catalyzed carbonphosphonation of α,α-diaryl allylic alcohols is achieved. A series of γ-ketophosphonates with different substituents were readily obtained. The mechanistic study indicated that the reaction was initiated by the addition of P-radicals, which sequentially undergo 1,2-migration of an aryl group to form C(Ar)–C(sp³) bonds.
