72% | With copper(ll) sulfate pentahydrate; ammonia; water; zinc; at 70 - 85℃; for 7.5h; | Anthraquinone-2-carboxylic acid (2) (0.5 g, 2 mmol), zinc dust (2.6 g, 40 mmol), CuSO4 .5H2 O (0.1 g, 0.4mmol), and aqueous ammonia (35 mL, 26percent) were added to a 100-mL flask. The reaction mixture was stirredwith a magnetic stirrer under reflux at 70 C for 5.5 h. Then the reaction temperature was increased to 85 Cand kept for 2 h at this temperature. The completed hot reaction mixture was filtered to remove insolubleresidues and the filtrate was cooled. After that, the filtrate was acidified with dilute HCl (1:1) until pH wasbetween 4 and 5. The precipitated yellow solid was filtered and dried in a freeze dryer. Then the yellow solid wasrecrystallized in acetic acid. The reaction was completed with 72percent yield. 1 H NMR (400 MHz, DMSO-d6) 8.76 (s, 2H), 8.62 (s, 1H), 8.30?7.92 (m, 4H), 7.66-7.50 (m, 2H). 13 C NMR (100 MHz, DMSO-d6) 167.4,132.5, 132.1, 131.6, 131.5, 130.0, 128.5, 128.5, 128.3, 128.1, 127.5, 127.5, 126.7, 126.0, 124.1. |
