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. 32692-19-6, name is 5-Nitroindoline, This compound has unique chemical properties. The synthetic route is as follows., Formula: C8H8N2O2
General procedure: To a stirred solution of aryl halides (1.0 mmol) and indoline/indoline carboxylic acid (1.0 equiv) in dry DMSO (2.0 mL) at rt was added nano CuO (5.0 mol %) followed by Cs2CO3 (2.0 equiv) and heated at 80 C for 8 h. The progress of the reaction was monitored by TLC. After the reaction was complete, the reaction mixture was cooled to room temperature and catalyst was filtered, the crude residue was extracted with ethyl acetate (3 ¡Á 10 mL). The combined organic layers were extracted with water, saturated brine solution, and dried over anhydrous Na2SO4. The organic layers were evaporated under reduced pressure and the resulting crude product was purified by column chromatography by using ethyl acetate/hexane (7:3) as eluent to give the corresponding N-substituted indoles in excellent yields. The identity and purity of the product were confirmed by 1H, 13C NMR, and mass spectra.
According to the analysis of related databases, 32692-19-6, the application of this compound in the production field has become more and more popular.
