It is a common heterocyclic compound, the isothiazole compound, Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide, cas is 27148-03-4 its synthesis route is as follows.
A solution of thiosaccharin (tsacH) (0.04 g, 0.24 mmol) in methanol (8 cm3) was added to a solution of K2[PtCl4] (0.05 g, 0.12 mmol) in water (3 cm3). The orange mixture was heated at reflux on a steam bath for 2 h. After cooling to room temperature the brown solid formed was filtered off, washed with water and dried in a vacuum oven to give 1 (0.049 g, 70%). 1H NMR (d6-dmso): delta 8.50 (d, J 7.0 Hz, 2H), 8.86 (d, J 6.8 Hz, 2H), 7.76 (m, 4H); IR v/cm-1; IR(KBr) 3085w, 1419s, 1340vs, 1100vs, 1012s, 804vs, 366m cm-1; Elemental Anal. Calc. for PtS4N2O4C14H8·H2O. Found: C, 27.58 (27.63); H, 1.64 (1.49); N, 4.60 (4.59)%.
