When all the substituted benzene has been added (∼30 min), the reaction mixture was stirred for 4 h. The reaction mixture was then poured over ice cold water and kept overnight in the refrigerator. The precipitate formed was filtered and washed with water (2 * 10 mL) to afford the titled products (3a-c).

Representative procedure for the synthesis of sulfonyl chlorides from the reaction of NaOCl•5H2O with thiols: To a solution of p-methylbenzenethiol (248.4 mg, 2.0mmol) in acetic acid (11 mL), NaOCl•5H2O (1.32 g, 12.0mmol) was added and stirred at room temperature for 1min. Saturated aqueous sodium thiosulfate (4 mL) and dichloromethane (20 mL) was added to the reaction mixture. The organic layer was separated and the aqueous phase was extracted with dichloromethane (20 mL). The extracts were dried over anhydrous sodium sulfate, and evaporated to afford p-toluenesulfonyl chloride (328.9 mg, 86percent) as colorless crystals. This product is pure enough without further purifications, and is consistent with the commercial reagent.

To this was added 388.4 mg (2.0 mmole) sodium para-toluenesulfonate, 213 mg (0.72 mmole, 0.36 molar) of bis (trichloromethyl) carbonate and 1.38 g (6 mmole, 3 molar) of potassium tertiary phosphate monohydrate Stir for 5 minutes.When two drops of triethylamine (about 20 mg, 0.10 mole ratio) were added thereto, it was also observed that bubbles were generated in the reactor as in Example 1. [The ice-bath was then removed and the temperature was raised to room temperature 30 minutes moreAfter confirming the completion of the reaction, the reaction mixture was filtered and washed with dichloromethane (10 mL) to remove unreacted salts, and the resulting solution was distilled under reduced pressure to obtain the desired compound, para-toluenesulfonyl chloride 355 Mg (yield: 93percent).

Yield 74 %

Conditions & References General procedure for the chlorination of isatin-3-p-toluenesulfonyl hydrazones: General procedure: Into a flame-dried round bottom flask was added the isatin-3-p-toluenesulfonylhydrazone derivative 13 (0.2 mmol, 1.0 eq.) and to this was added DCE (0.2 M, 1.0 mL).The resulting slurry was stirred at room temperature under a nonrigorous nitrogenatmosphere and to it was added pyridine (5 molpercent, 8 μL as a 10percent solution in DCE), afterwhich the reaction mixture was immersed in an 85-88 °C sand or oil bath. To this wasadded PhICl2 (2.5 eq., 0.5 mmol, 138 mg), and the reaction mixture was stirred until ahomogeneous mixture was produced and gas evolution ceased. This was deemed the endpoint for the reaction, and was subsequently confirmed by TLC analysis, which indicatedthe consumption of starting material. The reaction mixture was added directly onto acolumn and purified by gradient column chromatography using EtOAc/Hexanes as theeluent. All 3,3-dichloro-2-oxindole products were consistent with those previouslyreported in the literature.6 With pyridine, (Dichloroiodo)benzene in 1,2-dichloro-ethane, Time= 0.0166667h, T= 20 - 88 °C , Inert atmosphere, Reflux Hepples, Charlotte; Murphy, Graham K.; Tetrahedron Letters; vol. 56; nb. 35; (2015); p. 4971 - 4974; Art.No: 46455 View in Reaxys

Then, 105 mL of toluene was charged, and 10.3 g (0.1456 mole, 1.04 times moles) of chlorine was, little by little, blown into the reactor at a temperature of 18 to 20 °C. The reaction solution was aged at the same temperature of 18 to 20 °C with stirring, and separated into an organic layer and an aqueous layer. The organic layer was washed with 90 g of a 3percent aqueous sodium chloride solution and then concentrated at a reduced pressure and 45°C or less to obtain 32. 9 g of a benzenesulfonyl chloride solution. Gas chromatographic quantitative analysis revealed that the concentration of benzenesulfonyl chloride in the organic layer was 70.7percent (weight; 24.21g, 0.1371 mole), and the yield was 93.9percent.
