Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 18711-13-2, name is 4,7-Dichloroindoline-2,3-dione, This compound has unique chemical properties. The synthetic route is as follows., Quality Control of 4,7-Dichloroindoline-2,3-dione
General procedure: alpha-Isothiocyanato imide 2c (10.7 mg, 0.050 mmol) and catalyst 6d (2.8 mg, 0.005 mmol, 10 mol %) were dissolved in diethyl ether (1.0 mL) in a glass vial while stirring. Isatin 1a (8.8 mg, 0.060 mmol) was added and the mixture was further stirred at room temperature for 2 h. The reaction progress was monitored by TLC analysis. Upon completion, the solvent was removed under reduced pressure and the crude product was purified by flash column chromatography on silica gel (1:1 hexane/ethyl acetate) to give the desired product.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 18711-13-2.
