Herein, we developed alkyl radical generation from C(sp3)–H bonds of alkanes via a photoinduced HAT-process without employing an external metal, photocatalyst, and organic peroxide. The generated participates in addition cascade cyclization N-arylacrylamides/N-acryloyl benzamides to deliver structurally diverse valuable functionalized oxindoles isoquinolinediones moderate good yields. Preliminary mechanistic studies indicated the aryl through homolytic cleavage Ar–I direct photoexcitation iodide.

An efficient bifunctional ionic-liquid-induced electrochemical C-H arylation of quinoxalin(on)es with aryltriazenes has been developed. The reaction utilizes as stable reagents and ionic liquids promoter electrolyte. Various arylated quinoxalin-2(1H)-ones, quinoxaline 2-methyldibenzo[f,h]quinoxaline were assembled in modest to excellent yields under mild, metal- oxidant-free conditions. developed protocol features simple operation, good functional group tolerance, selectivity, product derivatization, practical gram-scale synthesis batch continuous-flow processes.

Visible light-induced radical 5/6-endo-trig difluoroalkylation/cyclization of N-allyl and homoallyl aldehyde hydrazones with various fluoroalkyl bromides has been achieved. The reaction was carried out alkyl difluoroacetates difluoroacetamide as difluoroalkylation reagents Eosin Y an organic photocatalyst. Various difluoroalkylated dihydropyrazoles tetrahydropyridazines were obtained under metal-free mild conditions.
