27148-03-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide, cas is 27148-03-4,the isothiazole compound, it is a common compound, a new synthetic route is introduced below.

The [Zn(tsac)2(o-phen)] complex was prepared by addition of a dissolution of Zn(NO3)26H2O (14.85 mg, 0.049 mmol, 2 ml) into a thiosaccharine solution (20 mg, 0.1 mmol/ethanol:water 1:1,2 ml). A o-phenantroline solution was finally added drop by drop (ethanol:water 1:1, 2 ml) and a yellow power was obtained. The resulting yellow solid was filtered and washed with cold water. Crystals suitable for X-ray diffraction studies were produced by slow diffusion of diethyl ether to the mother solution. Yield: 74% Molar Conductivity (mS M1) = 22.4. Calculated analytical percent composition for C26H16N4O4S4Zn: C = 48.516%; H = 2.267%; N =8.592%; Found: C = 48.638%; H = 2.511%; N = 8.725%. Soluble indimethyl sulfoxide and dimethyl formamide. Non-soluble in other solvents (methanol, chloroform, dichloromethane, acetone, water). UV-Visible [DMSO, kmax nm]: 341. 1HNMR (300 MHz,DMSO) d 8.72-9.21 (m, 1H), 8.94 (m, 1H), 8.31(m, 1H), 8.03-8.21 (m, 1H), 7.91 (m, 1H), 7.57-7.72 (m, 3H). 13CNMR (75 MHz, DMSO) d 191.81 (C1), 149.09 (C8), 140.02 (C10), 139.36(C12), 137.94 (C7), 136.52 (C2), 132.12 (C4), 130.91 (C5), 128.70 (C11), 127.37 (C13), 125.10 (C3), 125.81 (C9), 119.03 (C6).

The chemical industry reduces the impact on the environment during synthesis,27148-03-4,Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide,I believe this compound will play a more active role in future production and life.
