Huang, Xiang published the artcileVisible-Light-Catalyzed in Situ Denitrogenative Sulfonylation of Sulfonylhydrazones, Recommanded Product: Phenyl(pyridin-2-yl)methanone, the publication is Organic Letters (2021), 23(17), 6784-6788, database is CAplus and MEDLINE.
A photocatalyzed in situ denitrogenative sulfonylation of N-arylsulfonyl hydrazones was developed to afford (arylsulfonylalkyl)arenes I [R1 = Ph, 2-MeC6H4, 1-naphthyl, etc.; R2 = H, Me, Ph; R3 = 4-MeC6H4, 4-BrC6H4, 2-naphthyl, etc.]. This transformation provided a low-carbon strategy to assemble arylalkyl sulfones in a stepwise denitrogenation/sulfonylation manner.
