Synergistic Combination of Visible-Light Photo-Catalytic Electron and Energy Transfer Facilitating Multicomponent Synthesis of Β-Functionalized Α,α-Diarylethylamines

A synthetic strategy with the visible-light photo-catalytic synergistic combination of electron and energy transfer processes has been developed. The mild reaction conditions allow the radical-radical cross-coupling phenomenon for the multicomponent synthesis of β-arylsulfonyl(diarylphosphinoyl)-α,α-diarylethyl-amines from readily available arylsulfinic acids (diarylphosphine oxides), 1,1-diarylethylenes and arylazides.
