YieldReaction ConditionsOperation in experiment
With hydrogen fluoride; at 0 - 50℃; under 4 - 5 Torr; 1040g of mixture obtained with the reaction of step (a) were introduced into a 3-litre steel reactor, and the system was cooled to 0-3C under stirring. Metering of the hydrofluoric acid in portions of 70 ml each for a total amount of 280 g was started. During addition, the vent of the reactor was left open; at the end of the addition it was re-closed, and the internal pressure was allowed to rise to 4-5 atm. After approximately 15 minutes following upon each addition, the hydrochloric acid formed was vented, and a fresh addition of hydrofluoric acid was made. At the end of this addition, the reaction mixture was heated to approximately 50C to remove any excess of hydrofluoric acid. The product was purified by distillation, first eliminating the residual hydrofluoric acid, and rectification was performed to obtain the product of the titre. There were obtained 1805 g of the product with a purity of 99.9 % (GC). The global yield of chlorination, fluorination and distillation was 83%.
With 2,4-dichloro-benzotrifluoride; hydrogen fluoride; at 0 - 50℃; under 3040.2 - 3800.26 Torr; 846 g of mixture obtained with the reaction of step (a) were introduced in a 3-litre steel reactor, and the system was cooled to 0-4C under stirring. Metering of the hydrofluoric acid in portions (70 ml, 80 ml, 80 ml) was started for a total amount of 230 g. During the addition, the vent of the reactor was left open; at the end of the addition, it was re-closed, and the internal pressure was allowed to rise to 4-5 atm. After approximately 15 minutes following upon each addition, the hydrochloric acid formed was vented, and a new addition of hydrofluoric acid was performed. At the end of this operation, the reaction mixture was heated to approximately 50C to remove the excess hydrofluoric acid. The product was purified by distillation, first eliminating the residual hydrofluoric acid, and rectification was then performed to obtain the product of the titre. There were obtained 373 g, with a purity of 99.9 % (GC). The global yield of chlorination, fluorination and distillation was 85%.
28.8 g With hydrogen fluoride; for 2h; 24 ml (0.2 mol) of a pepper ring was added to a 250 ml lined PTFE stainless steel flask,Phosphonium chloride 97.6g and phosphorus pentachloride 83.3g (0.4m0l), the temperature rose to reflux reaction, GC detection of raw material pepper ring content of less than 0.2% reaction end; the reaction solution distillation distillation distillation of by-product three Phosphorus chloride and solvent phosphorus oxychloride, vacuum distillation temperature of 110 C, vacuum degree of -0.095MPa; vacuum distillation after the end of cooling to 4 C, in the vacuum of -0.095MPa drop Plus hydrogen fluoride liquid 8g (0.4mol), dropping finished, incubated for 2 hours, and then release the by-product of hydrogen chloride, and then add saturated sodium carbonate solution, adjust the solution PH value of 6.5 ~ 7.5, stirring 0.5 hours, , The organic layer was distilled after the colorless transparent liquid for the finished 2,2 - difluoro - 1, 3 - benzodiazepine 28.8g, yield 99.8%, GC purity 99.8%
YieldReaction ConditionsOperation in experiment
Example 10 60 g of dichlorobenzodioxole at 130 C. were placed in a stirred apparatus equipped with a chlorine inlet, a metering device, a high-efficiency condenser and a gas outlet, and a solution of 1.8 g of azobisisobutyronitrile in 122 g of benzodioxole was then metered in over a period of 3 hours and 150 g of chlorine were introduced at the same time. When the metering had ended, the mixture was purged at 130 C. with nitrogen. 228 g of 2,2dichlorobenzodioxole with a boiling point of 81-90 C at 12 mbar were obtained. The crude product of the chlorination (250 g) could be used without further purification in a fluorination for the preparation of 2,2-difluorobenzodioxole.

YieldReaction ConditionsOperation in experiment
With potassium fluoride; In hexanedinitrile; A mixture of 300.0 grams (1.57 mole) of 2,2-dichloro-1,3-benzodioxole, 273.7 grams (4.71 mole) of potassium fluoride, and 3.0 grams of l,4,7,10,13,16-hexaoxacyclooctadecane in 815 mL of adiponitrile was warmed to 120 C. during a 30 minute period. After this time an additional 3.0 grams of 1,4,7,10,13,16-hexaoxacyclooctadecane was added, and the heating was continued at 110 C. for an additional 9.5 hours. The reaction mixture was cooled and distilled under reduced pressure to yield 302.7 grams of 2,2-difluoro-1,3-benzodioxole, b.p. 56-79 C./114 mm.
