| titleOfInvention | Synthesis method of 3,3',4,4',5,5'-hexafluorobiphenyl |
| abstract | The invention discloses a synthesis method of 3,3',4,4',5,5'-hexafluorobiphenyl. The synthesis method of 3,3',4,4',5,5'-hexafluorobiphenyl comprises the following step: performing Suzuki coupling reaction on 3,4,5-trifluorohalogenobenzene of Formula 1 and 3,4,5-trifluorobenzene boride of Formula 2 under the action of a palladium catalyst in the presence of an organic phosphine ligand, an additive and alkali in solvent, wherein X is chlorine, bromine or iodine, y is 1 or 2, OR is hydroxyl, or groups shown in the specification, C2-6 represents alkylidene, and C1-6 represents alkyl; when y is 1, OR is a group shown in the specification; when y is 2, OR is hydroxyl or a group shown in the specification; and the additive is a salt which has a general formula MnAm, wherein M is ammonium, lithium, sodium, potassium, iron or manganese, A is fluorine, chlorine, bromine, iodine, sulfate or acetate, n is 1 or 2, and m is 1, 2 or 3. |
