Visible photocatalysis of novel oxime phosphonates: synthesis of β-aminophosphonates

Abstract

A novel type of oxime phosphonate was synthesized and used in the intermolecular cascade radical addition reaction of alkenes to access β-aminophosphonates via visible-light-driven N-centered iminyl radical-mediated and redox-neutral selective C–P single-bond cleavage in an active phosphorus radical route. The procedure is characterized by its ability to achieve the construction of Csp³–P and Csp³–N bonds without the requirement for oxidants and bases.
