Name is Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide, as a common heterocyclic compound, it belongs to isothiazole compound, and cas is 27148-03-4, its synthesis route is as follows.,27148-03-4
Room temperature: To a benzene solution (20mL) containing [Os3(CO)10(NCMe)2] (0.13g, 0.14mmol) was added tsacH (56g, 0.28mmol), after which the solution was allowed to stir at room temperature for 2h. TLC examination of the reaction revealed the presence of two new products in a 3:1 ratio representing 1 and 2, respectively. The products were isolated by chromatography using an eluent composed of cyclohexane/ CH2Cl2 (1:1, v/v) that afforded two bands corresponding to [HOs3(CO)10(mu-N,S-1,3-tsac)] (2) (32mg, 22%) and [HOs3(CO)10(mu-S-tsac)] (1) (0.10g, 68%) in order of elution. Each product was obtained as orange crystals after recrystallization from n-hexane/CH2Cl2 at 4C. Data for 1: Anal. Calc. for C17H5NO12Os3S2: C, 19.44; H, 0.48, N, 1.33. Found: C, 19.92; H, 0.54, N, 1.36%. IR (nuCO, CH2Cl2): 211m, 2076vs, 2066s, 2028s, 2019s, 1992m cm-1. 1H NMR (CDCl3): delta 8.00 (m, 1H), 7.90 (m, 1H), 7.86 (m, 2H),-17.10 (s, 1H). Data for 2: Anal. Calc. for C17H5NO12Os3S2: C, 19.44; H, 0.48, N, 1.33. Found: C, 19.98; H, 0.52; N, 1.37%. IR (nuCO, CH2Cl2): 2113m, 2076s, 2065s, 2029s, 2018s, 1994w, 1982w cm-1. 1H NMR (CDCl3): delta 7.94 (d, J 7.2Hz, 1H), 7.84 (d, J 7.2Hz, 1H), 7.72 (m, 2H),-13.96 (s, 1H).
With the complex challenges of chemical substances, we look forward to future research findings about Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide
