| titleOfInvention | Bis- [the fluoro- 2- of 5- (4 '-methoxybenzoyl base)] biphenyl and its synthetic method |
| abstract | The invention discloses a kind of bis- [the fluoro- 2- of 5- (4 '-methoxybenzoyl base)] biphenyl and its synthetic methods.The method is the back flow reaction in thionyl chloride solution using the chloro- 2- fluobenzoic acid of 5- as presoma；It purifies to obtain the chloro- 2- fluorobenzoyl chloride of 5- as distilling the acyl chlorides monomer separation by obtained by, and in anhydrous AlCl 3 Under the action of carry out Fredel-Crafts with methyl phenyl ethers anisole and react, and recrystallization is carried out to product and handles to obtain the fluoro- 1- of the chloro- 2- of 5- (4 '-methoxybenzoyl base) benzene；The product issues raw intermolecular coupling reaction in Ni or Cu catalyst and corresponding inorganic salt action, and by being recrystallized to give bis- [the fluoro- 2- of 5- (4 '-methoxybenzoyl the base)] biphenyl of final product. |
