Extracurricular laboratory: Synthetic route of 27148-03-4

As the rapid development of chemical substances, we look forward to future research findings about 27148-03-4

Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide, cas is 27148-03-4, it is a common heterocyclic compound, the isothiazole compound, its synthesis route is as follows.,27148-03-4

The complex was synthesized by addition of 4,4′-trimethylenedipyridine (6.2 mg, 0.031 mmol) and thiosaccharine (12.7 mg, 0.0638 mmol), respectively, to a solution of Zn(NO3)26H2O (10.2mg, 0.0342 mmol) in ethanol:water (4 ml), and kept under mechanical stirring at room temperature. The resulting yellow solid was filtered off and washed with cold water. By slow evaporation of the mother solution single crystals appeared. They were washed with water and analysed using X-ray diffraction. Yield: 82%. Molar conductivity (mS M1) = 28.3. Analytical percent composition calculated for C27H22N4O4S4Zn: C = 49.127%; H = 3.359%;N = 8.487%. Found: C = 48.811%; H = 2.981%; N = 8.378%. Soluble in DMSO and DMF. Slightly soluble in water, ethanol, methanol, chloroform. Insoluble in acetone and methane dichloride. UV-Visible [DMSO, kmax nm]: 347.1H NMR (300 MHz, DMSO) d 8.46 (dd, 4H), 7.92 (m, 2H), 7.58-7.72 (m, 6H), 7.28 (dd, 4H), 2.64 (t, 4H), 1.93 (m, 2H). 13C NMR (75 MHz, DMSO) d 191.71 (C1), 151.07 (C10), 149.31 (C8), 137.98(C7), 136.56 (C2), 132.05 (C4), 130.82 (C5), 125.07 (C3), 124.04(C9), 119.01 (C6), 33.80 (C11), 30.12 (C12).
