A preparation process of a fluorine substituted aromatic compound comprising reacting an alkali metal or alkali earth metal salt of an aromatic compound having a hydroxy group with an organic fluorinating agent is disclosed. As a representative fluorinating agent, a bis-dialkylaminodifluoromethane compound, for example, 2,2'-difluoro-1,3-dimethylimidazolidine, is exemplified.
According to the process, an industrially useful fluorinated aromatic compound, for example, a fluorobenzene, a fluorine substituted benzophenone, a fluorine substituted diarylsulfone can be prepared with ease in economy without specific equipment.
本发明公开了一种氟取代芳香族化合物的制备工艺,该工艺包括使具有羟基的芳香族化合物的碱金属盐或碱土金属盐与有机氟化剂反应。作为氟化剂的代表,举例说明了一种双二烷基氨基二氟甲烷化合物,例如 2,2'-二氟-1,3-二甲基咪唑烷。
根据该工艺,工业上有用的氟化芳烃化合物,例如氟苯、氟取代的二苯甲酮、氟取代的二元砜,无需特定设备即可轻松制备,经济实惠。
