With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.27148-03-4,Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide,as a common compound, the synthetic route is as follows.
A CH2Cl2 solution (20mL) of [Ru3(CO)12] (100mg, 0.16mmol) and tsacH (63mg, 0.32mmol) was heated to reflux for 8h during which time the color of the solution changed from yellow to deep red. The reaction mixture was then allowed to cool at room temperature, and the solvent was removed under reduced pressure. The residue was separated by TLC on silica gel using a binary eluent composed of n-hexane/CH2Cl2 (v/v, 1:1), yielding a single yellow band corresponding to [Ru2(CO)6(mu-N,S-tsac)2] (1). The product was recrystallized from n-hexane/CH2Cl2 at 4C and furnished orange crystals of analytically pure 1 in 12% yield (14mg). Data for 1: Anal. Calc. for C20H8N2O10Ru2S4: C, 31.33; H, 1.05; N, 3.65. Found: C, 31.64; H, 1.12; N, 3.69%. IR (nuCO, CH2Cl2): 2102s, 2075vs, 2032sh, 2027s, 1961w cm-1. 1H NMR (CDCl3): delta 8.01 (d, J 7.2Hz, 2H), 7.88 (d, J 7.2Hz, 2H), 7.78 (t, J 7.2Hz, 2H), 7.73 (t, J 7.2Hz, 2H)., 27148-03-4
The synthetic route of 27148-03-4 has been constantly updated, and we look forward to future research findings.
