Dai, Shengfei published the artcileMetal-free and Selectfluor-mediated diverse transformations of 2-alkylthiobenzamides to access 2,3-dihydrobenzothiazin-4-ones, benzoisothiazol-3-ones and 2-alkylthiobenzonitriles, Recommanded Product: 1-Iodohexane, the publication is Organic Chemistry Frontiers (2022), 9(15), 4016-4022, database is CAplus.
Diverse transformations of 2-alkylthiobenzamides were established to synthesize 2,3-dihydrobenzothiazin-4-ones, benzoisothiazol-3-ones and 2-alkylthiobenzonitriles in the presence of Selectfluor. Both NaI-HI and TFA-Ac2O systems control the selective C-S bond cleavage and C-H bond functionalization to access 2,3-dihydrobenzothiazin-4-ones and 2-substituted 2,3-dihydrobenzothiazin-4-ones, resp. Notably, this was the first example of using Selectfluor as a methylene source to construct important 2,3-dihydrobenzothiazin-4-ones. In the presence of HCl, benzoisothiazol-3-ones were obtained in good yields. Furthermore, 2-alkylthiobenzonitriles could also be prepared using the same NaI-HI system via a thioether-directed and Selectfluor-mediated dehydration of 2-alkylthiobenzamides.
