1,3-Difluoro-2-iodobenzene Use and Manufacturing
To a solution of 1, 3-difluorobenzene (lO.OOg, 87mmol) in anhydrous THF (50 mL) was added n-BuLi (42mL, 105mmol) at -78°C under NTo a solution of 1, 3-difluorobenzene (10.00 g, 87 mmol) in dry tetrahydrofuran (50 mL) at -78 ° C under nitrogen2.5 mol / l n-butyllithium (42 mL, 105 mmol) was slowly added dropwise. Add to maintain at -78 ° C for 10 minutes and then warm to room temperature for 5 minutes. Then, a solution of iodine (26.7 g, 105 mmo 1) in tetrahydrofuran (200 mL) was slowly added dropwise to the above reaction solution, and the mixture was stirred at room temperature for 4 hours. After completion of the reaction, slowly add water to the quenching reaction, extraction with dichloromethane. The resulting organic phase was washed with saturated brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give 1, 3-difluoro-2-iodobenzene (12.5 g, 74percent).A
