Synthesis of Seleno Oxindoles via Iodine-induced Radical Cyclization of N-arylacrylamides with Diorganyl Diselenides

A mild radical cascade cyclization of N-arylacrylamides with diselenides for the preparation of oxindoles via iodine oxidation is disclosed, which provide an eco-friendly process for the construction of C–Se bond. 25 Examples of N-arylacrylamide substrates were investigated with excellent yields. Besides, the tandem cyclization of acrylamide with diphenyl disulfide was also applicable under the same condition.

Tandem cyclization/arylation of diaryliodoniums via in situ constructed benzoxazole as a directing group for atom-economical transformation

Linear diaryliodoniums often undergo only single arylation and leave equivalent aryliodide as waste. Herein, we demonstrate that linear unsymmetrical diaryliodoniums could be tuned by dual nickel/palladium metal system to accomplish...
