Fig. 5: Proposed mechanism of copper-catalyzed photoredox Chan-Lam coupling.
From: Autocatalytic photoredox Chan-Lam coupling of free diaryl sulfoximines with arylboronic acids
The reaction was initiated by a stoichiometric classical oxidative Chan-Lam coupling, and then entered the photocatalytic stage after N-arylted product 3 and NH-sulfoximine 1 binding to Cu(I) together to form the active photocatalyst E’.
