Synthetic Route of 2043-47-2 ,Some common heterocyclic compound, 2043-47-2, molecular formula is C6H5F9O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
18.8 g (71.1 mmol) of the fluorinated alcohol (Fluorochem Limited) and 8.63 g (85.3 mmol) of triethylamine are dissolved in 120 ml of dry toluene. 8.82 g (35.6 mmol) of 5- nitroisophthaloyl chloride is slowly added portionwise to the reaction mixture at 0-100C under nitrogen atmosphere. A large mass of a white solid is formed and as the reaction became difficult to stir, 280 ml of dry toluene is added. The reaction mixture is stirred at room temperature for 12 hours. Then water (300 ml) is added, the suspension is stirred for 1 hour and the solid is filtered off, washed repeatedly with water and dried in an oven to give14.9 g of the compound of formula 108, white solid, m.p. 91-92C. 1H NMR: (300 MHz, acetone-Gfe): delta = 9.00 (br s, ArH, 2H); 8.95 (br s, ArH, 1H); 4.83 (t, J = 6.0 Hz, OCH2CH2CF2, 4H); 3.05-2.80 (m, OCH2CH2CF2, 4H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 2043-47-2, 1H,1H,2H,2H-Nonafluoro-1-hexanol, other downstream synthetic routes, hurry up and to see.
