Aryl chlorides are more commercially available and lower cost compared with aryl bromides iodides. However, the use of (hetero)aryl as radical precursors for di(hetero)arylation alkenes remains an underdeveloped area. Furthermore, existing examples theses reactions predominantly confined to activated alkenes. In this study, we introduce a photoirradiation-promoted benzophenone-catalyzed 1,2-di(hetero)arylation process that is applicable both unactivated alkenes, utilizing cyanoarenes sources. Importantly, method allows simultaneous introduction two heterocycles high regioselectivity.

Simultaneous construction of two new C-C bonds in the alkene substrates regioselectively is significantly challenging. Herein, we report an unprecedented regioselective arylcarboxylation strategy activated alkenes with readily available aryl halides and tetrabutylammonium oxalate as reductant C1 source under visible-light-induced conditions. The reaction proceeds smoothly to access various carboxylic acids absence any catalysts, additives, metal promoters, or pre-established CO2 atmosphere. electron donor-acceptor (EDA) complex formed between stoichiometric amounts trigger single-electron reduction relay process after irradiation visible light. situ generated oxalic radical anion species undergoes homolysis bond releases potent source, respectively, facilitate reductive carboxylation.

Comprehensive Summary Herein, we report an efficient and practical protocol for the photoinduced dehalocyclization of ortho ‐halophenylacrylamides with formate by engagement a CO 2 radical anion to access substituted oxindoles. This method proceeds smoothly under mild conditions exhibits wide range substrate as well remarkable functional group compatibility.
