Visible light-mediated oxidative C(sp3)–H phosphonylation for α-aminophosphonates under oxidant-free conditions

Abstract

An external oxidant-free synthesis of α-aminophosphonates by synergistically combining photocatalysis and proton-reduction catalysis is developed herein. The gram-scale experiment demonstrates the potential utility of this protocol. This study may have important implications for the functionalization of oxidant-sensitive C(sp³)–H bonds.
