As a common heterocyclic compound, it belong isothiazole compound,Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide,27148-03-4,Molecular formula: C7H5NO2S2,mainly used in chemical industry, its synthesis route is as follows.,27148-03-4
A Zn(NO3)2*6H2O dissolution (10.3 mg, 0.0346 mmol/2 ml ethanol:water 1:1) was added to another dissolution of thiosaccharine (12.3 mg, 0.062 mmol/2 ml ethanol:water 1:1). Finally, solid 2,2′-biquinoline was added (9.4 mg, 0.0367 mmol/2 ml ethanol:water1:1). A pale yellow powder was then obtained. Yield: 90%. Molar conductivity (mS M1) = 26.3. Analytical percent composition calculated for C32H20N4O4S4Zn: C = 53.520%; H = 2.807%; N = 7.801%. Found: C = 53.884%; H = 2.761%; N = 7.698%. Soluble in DMSO and DMF. Almost insoluble in water, ethanol, methanol, acetone, dichloromethane and chloroform. [DMSO, kmaxnm]: 339 1H NMR (300 MHz, DMSO) d 8.80 (dd, 1H), 8.58 (dd, 1H), 8.19(dd, 1H), 8.08 (dd, 1H), 7.89-7.95 (m, 1H), 7.85 (td, 1H), 7.53-7.73 (m, 4H). 13C NMR (75 MHz, DMSO) d 191.54 (C1), 155.21(C16), 147.16 (C8), 137.80 (C7), 137.36 (C14), 136.32 (C2), 132.16 (C4), 130.99 (C5), 130.18 (C10), 129.31 (C12), 128.16 (C13), 128.03(C11), 127.42 (C9), 125.10 (C3), 119.05 (C6), 118.87 (C15).
With the synthetic route has been constantly updated, we look forward to future research findings about Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide,belong isothiazole compound
