Adding a certain compound to certain chemical reactions, such as: 51762-67-5, name is 3-Nitrophthalonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 51762-67-5, category: nitriles-buliding-blocks
General procedure: 8-hydroxyquinoline-5-sulfonic acid (1.30 g, 5.78 mmol) was dissolved in dry DMF (8.00 mL) at 45 C and anhydrous K2CO3(1.5 g, 11.56 mmol) was added. After stirring for 15 min, 3-nitrophthalonitrile (1) was added dropwise in 2 h with efficient stirring. The reaction mixture was stirred under nitrogen at 45C for 4 days. After being cooled to room temperature, the mixture was poured into ca. 200 mL ice-water media and 1 M HCl (50 mL)was added in it. After completion of the precipitation approximately in 0.5 h, the creamy precipitate that formed was filtered and then washed with ca. 100 mL water until the washings became neutral. Column chromatography with methanol/dichloromethane (5:1) eluent on silica gel was employed to obtain the pure product. As expected, the yellow products were soluble in DMF and DMSO. Yield of 1: 1.36 g (67%); m.p.: Anal. Calc. for C17H9N3O4S (Mw:351.34): C, 58.12; H, 2.58; N, 11.96. Found: C, 57.90; H, 2.56; N,11.81%. FT-IR (KBr disc) n/cm-1: 3082, 3027, 2980 (Ar H), 2240 (CN), 1590, 1574, 1550 (Ar), 1273 (ArOAr), 1191, 1154 (SO2),789, 774, 674. 1H NMR (DMSO-d6): d ppm = 7.10-9.50 (m, 8H, ArH). UV/vis (DMSO): lambdamax = 299, 259.
