YieldReaction ConditionsOperation in experiment
21.4 g 2), taking 0.15 mol of n-decyl methyl sulfide and 0.15 mol of dimethyl sulfate dissolved in 100 ml of 1,2-dichloroethane, and heating under reflux (about 70-80 ° C) for 2 h;   After the reaction, distillation under reduced pressure (0.1 MPa pressure, Distillation temperature of 45 ° C) 1,2-dichloroethane, A sulfonium salt to obtain a reaction product (C8H18 (CH3) 2SCH3SO4) of Used directly in the next step. 3), sequentially adding a reaction product containing a sulfonium salt in 100 ml of toluene (containing 0.15 mol of sulfonium salt), 0.7 mol of sodium hydroxide, 0.1 mol of <strong>[342-25-6]2,4'-difluorobenzophenone</strong>, stirred, and the reaction temperature was controlled at 65 ° C. After reacting for 4 hours, add 100 ml of water after the reaction, and dispense. The organic phase (located on the upper layer) is washed three times with water (50 ml per wash). Water removal (separation extraction), drying (adding 1 g of anhydrous sodium sulfate for drying), Filtration (to remove sodium sulfate), and the resulting filtrate was then distilled under reduced pressure. (0.1MPa pressure, 80 ° C distillation temperature) recovery of toluene, 21.4 g (0.09 mol) of 1-(2-fluorophenyl)-1-(4-fluorophenyl)ethylene oxidewas obtained. The yield of 1-(2-fluorophenyl)-1-(4-fluorophenyl)oxirane prepared by the above method was 92percent. The purity is 95percent.
