Visible Light Induced C-H/N-H and C-X Bonds Reactions

Herein, we report efficient visible light-induced photoredox reactions of C–H/N–H and C–X Bonds. These methods have provided access to varied portfolio synthetically important γ-ketoesters, azaspirocyclic cyclohexadienones spirocyclohexadienones, multisubstituted benzimidazole derivatives, substituted N,2-diarylacetamide, 2-arylpyridines 2-arylquinolines in good yields under mild conditions. Moreover, successfully discussed the construction through light-induction by an intermolecular radical addition, dearomative cyclization, aryl migration desulfonylation. Similarly, also spotlight light-catalyzed aerobic C–N bond activation from well-known building blocks elimination aromatization. The potential use a wide simple ketones available primary amines has made this transformation very attractive.
