2,5-DICHLOROFLUOROBENZENE

CLEAR COLORLESS LIQUID

General procedure: 14 Typical continuous diazotization procedure: Material A (50 mL of aqueous solution containing amine (100 mmol), fluoroboric acid (120 mmol), hydrochloric acid (180 mmol)), and material B (50 mL of aqueous solution containing sodium nitrite (105 mmol)) were pumped into the T-joint at 4 mL/min, respectively, after a residence time of about 15 s at 25 °C in a reacting tube, the mixture flowed through the outlet and accumulated in the cooling vessel. Vigorous stirring was maintained. The solid was filtered with suction after the slurry was cooled to −5 °C. The solid was washed with methanol and then dried in vacuo to yield the corresponding diazonium tetrafluoroborate. 15 Typical continuous fluorodediazoniation procedure: Slurry of the diazonium tetrafluoroborate prepared as above in 300 mL of cosolvent was introduced into a reacting tube continuously at a flow rate of 4 mL/min. The mixture was maintained for 1 min at setting temperature and then cooled in the tandem tube. The collected liquid was washed with aqueous NaOH and water, nearly colorless liquid was obtained.
