YieldReaction ConditionsOperation in experiment
84% With bromine In chloroform at 50℃; Reflux;
83% With bromine In chloroform at 50℃; Reflux; 4.2 Step 2: Synthesis of [Intermediate 5-b] Add compound 5-a (15g, 66.5mmol) and chloroform (100mL) to a 500mL three-necked flask in turn. The temperature is raised to 50, and a solution of bromine (8mL, 309mmol) in chloroform (100mL) is dropped very slowly. Reflux for 24-36h. After the reaction is completed, the temperature is lowered to 0°C, filtered, and the filter cake is washed three times with chloroform. The solid was collected, washed with saturated sodium thiosulfate solution, filtered, and the solid was collected, then washed with methanol and dichloromethane, and filtered to obtain a brown solid 5-b (12.5 g, 83% yield).

17 g With bromine; acetic acid at 60 - 70℃; for 16h; 1.1 (1) Preparation of 2,6-diaminobenzo (1,2-d; 4,5-d) dithiazole (the compound of the formula 3) In a 500 mL three-necked flask equipped with a reflux condenser and a dropping funnel, Add 21.6g (0.2moL) of p-phenylenediamine, 120 mL of water removed from 02, 28. OmL concentrated hydrochloric acid and 30.4 g (0.4 mol) ammonium thiocyanate, The above mixture was refluxed at 80-90 ° C for 24 h, and after cooling, the precipitate was collected by filtration. Then washed three times with hot water and dried in vacuum. 36. Og of pale yellow solid p-dithiourea (the compound of formula 2) is obtained. In a 500mL three-necked flask, 22,6 g (0.1 mol) of p-dithiourea (the compound of formula 2) and 180 mL of glacial acetic acid were added, and then 10 ml of a solution of bromine dissolved in 120 mL of glacial acetic acid was weighed. Slowly (about 60 minutes) added dropwise to the above reaction mixture, Keep the reaction temperature at 60-70 ° C, stir the reaction for 16 h, Pour the mixture into cold water and add ammonia to the mixture with vigorous stirring. Adjust the pH to 9-10, let stand, wait for the solution to cool, then filter, Wash with water until neutral, dry to give a crude product. The crude product was aged in hot DMF for 30 min, cooled and filtered. Wash with acetone, The yellow needle crystal 2,6-diaminobenzo (1,2-d; 4,5-d) dithiazole (the compound of the formula 3) was obtained in an amount of 17.00 g.
With bromine In chloroform at 50℃; for 24h; Reflux; 2.4.2. Synthesis of 2,6-Diaminobenzo [1,2-d:4,5-d'] bisthiazole (DABBT) The compound DABBT was synthesized according to the proceduredefined in [45] with some modifications. To a stirred suspension of 22.6 g (100 mmol) of PBTU in 105.6 mL of dry chloroform, 12.5 mLsolution of (6.24 mmol of Br2) of bromine in 19 mL of chloroform wasadded such that the pot temperature remained 350 °C. FT-IR spectrum (cm-1, Fig. 1b): 3390, 3270, and3173 cm-1 υ (NH and NH2), 3052 cm-1 υ (Ar-CH), 1637 cm-1 υ(C=N), 1539 cm-1 υ (C=C), 1436, 1316, 1114, 1068 cm-1 (C=S),858, 616, 504 cm-1.

YieldReaction ConditionsOperation in experiment
89% With trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane; water; potassium hydroxide In acetonitrile at 20℃; for 0.333333h; 4.2. Typical procedure for desulfurization of thiourea derivatives 1a-1s to oxoanalogs 2a-2s To a stirred solution of phenylthiourea 1 (1mmol) and 5% aq. KOH (5 mL) in acetonitrile (5 mL) was added DHPDMDO (0.332 g, 2mmol). The resulting mixture was allowed to stir at room temperature for an appropriate time (Table 2). After completion of the reaction as monitored by TLC, the reaction mixture was diluted with water (10mL) and the product was extracted in dichloromethan (3×5mL). The combined organic layer was washed with water (2×5mL) and dried over anhydrous Na2SO4. Evaporation of the solvent under reduced pressure gave almost pure products. Structures of the known products were established on the basis of their physical and spectroscopic (IR, 1H-NMR and 13C-NMR) data, which were consistent with those reported.[34,61]
