As a common heterocyclic compound, it belongs to isothiazole compound, name is Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide, and cas is 27148-03-4, its synthesis route is as follows.,27148-03-4
A solution of thiosaccharin (tsacH) (0.084 g, 0.425 mmol) in chloroform (10 cm3) was added to a solution of [Pt(kappa2-dppm)2]Cl2 (0.22 g, 0.22 mmol) in chloroform (10 cm3). A few drops of triethylamine were added and the resulting mixture was heated under reflex for 1 h. This produced a yellow solution which was filtered and reduced to half volume. Methanol (2 cm3) was added and the mixture was set aside to evaporate slowly at room temperature. The pale yellow crystalline solid thus formed was filtered off and dried in a vacuum oven (85%). 11: pale yellow solid, 85% yield. 1H NMR: delta 7.57 (d, J 7.60 Hz, 4H, Ar), 7.50-6.80 (m, 44 H, Ar), 3.46 (br, 4H, CH2); 31P{1H} NMR: 253 K 18.1 (br), -30.4 (br) ppm; 298 K 16.8 (vbr), -28.1 (vbr) ppm; 333 K -23.3 (vbr) ppm; IR(KBr) 3053w, 2932w, 1431s, 1313vs, 1159vs, 994s, 800s, 694s, 378m cm-1; Elemental Anal. Calc. for PtN2S4P4O4C64H52¡¤0.5CH2Cl2. Found: C, 55.42 (55.00); H, 3.79 (3.66); N: 2.00 (1.97)%.
With the complex challenges of chemical substances, we look forward to future research findings about 27148-03-4,belong isothiazole compound
