641-70-3, 3-Nitrophthalic anhydride is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: A mixture of a cyclic anhydride 1 (1 mmol), guanidiniumchloride (2) (1 mmol), Et3N (2 mmol) and FeCl3 (10 mol%)in PEG-400 (0.5 mL) at 60C for aromatic derivatives andat 100C for aliphatic derivatives was stirred for an appropriatetime. The reaction progress was monitored by thinlayerchromatography. After the completion of the reaction,the reaction mixture was cooled to room temperature andthen was extracted with H2O and EtOAc. The organic layerwas dried over MgSO4 and then evaporated under reducedpressure. The residue was purified by column chromatographyon silica gel using n-hexane-EtOAc (7:3). The desired1H-isoindole-1,3(2H)-diones were obtained in 70-95%yields. Spectroscopy data for compounds 3 are in goodagreement with those previously reported.
641-70-3 3-Nitrophthalic anhydride 21631, abenzofuran compound, is more and more widely used in various.
