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. 111771-08-5, name is 2-Fluoro-6-iodobenzoic acid, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 2-Fluoro-6-iodobenzoic acid
Method B: 2-Fluoro-6-[1 ,2,3]triazol-2-yl-benzoic acid. To a 2 L, 3- necked, round-bottomed flask equipped with an overhead mechanical stirrer, thermocouple probe, heating mantle, reflux condenser, and nitrogen inlet were added 2-fluoro-6-iodobenzoic acid (127.6 g, 480 mmol), copper iodide (4.57 g, 24 mmol), and Cs2C03 (312.6 g, 959 mmol). To these solids were added dioxane (640 mL), then water (2.6 mL, 144 mmol), then 1 H-1 ,2,3-triazole (55.6 mL, 959 mmol), and finally frans-1 ,2-dimethylcyclohexane-1 ,2-diamine (15.1 mL, 96 mmol). The mixture was then warmed to 60 C for 30 min, then to 83 C for 30 min, and then to 100 C for 3 h. After the 3 h at 100 C, the mixture was cooled and then 1 L of MTBE and 1 L of water were added. After vigorous mixing, the layers were separated and the bottom aqueous layer was acidified to pH 1 .72 with -148 mL of concentrated hydrochloric acid. The aqueous was then extracted twice with EtOAc. The combined organic layers were dried over Na2S04, filtered, and concentrated to provide a dark oil. The oil was stirred overnight in EtOAc (450 mL) and the resulting precipitate was removed by filtration. The mother-liquors were concentrated to a brown solid (106.21 g, 75 wt% by quantitative HPLC, 79.7 g, 80%). 1H NMR (400 MHz, DMSO-d6): 8.22 – 8.13 (bs, 2H), 7.84-7.80 (m, 1 H), 7.74 – 7.65 (m, 1 H), 7.50 – 7.41 (m, 1 H).
According to the analysis of related databases, 111771-08-5, the application of this compound in the production field has become more and more popular.
