Reactions of chalcone with imino-λ3-iodanes under oxidative conditions
摘要
The pathway of the reactions of imino-λ3-iodanes PhI=NSO2R (R = CF3, 4-MeC6H4) with chalcone depends on the nature of the oxidizing agent and the solvent. The reactions with halogen-containing oxidizers afforded a wide range of derivatives, including halo amides, halo amidines, 1,2-disubstituted imidazoline, and the 1,2-diamination product, depending on the solvent (acetonitrile or dichloromethane).
