| titleOfInvention | A kind of synthetic method of 2,2',3,3',5,5',6,6'-octafluoro-4-halobiphenyl |
| abstract | The invention discloses a method for synthesizing 2,2',3,3',5,5',6,6'-octafluoro-4-halogenobiphenyl, which belongs to the technical field of chemical synthesis. 2,3,5,6-tetrafluoro-1,4-dihalobenzene is subjected to magnesium reaction in an inert solvent to obtain 2,3,5,6-tetrafluoro-4-halophenyl magnesium halide, the obtained 2,3,5,6-tetrafluoro-4-halophenylmagnesium halide, in an inert solvent, in the presence of copper catalyst and oxygen, through self-coupling reaction to give 2,2',3,3',5 ,5',6,6'-octafluoro-4,4'-dihalogenobiphenyl, and then selectively dehalogenated to obtain 2,2',3,3',5,5',6,6' -Octafluoro-4-Halobiphenyl. The invention has the advantages of cheap and easy-to-obtain raw materials, short reaction steps, high synthesis yield, good product quality and the like, and is suitable for industrial production and application. |
