| titleOfInvention | Synthetic method of 2,3,5,6-tetrafluoro terephthalyl alcohol |
| abstract | The invention discloses a synthetic method of 2,3,5,6-tetrafluoro terephthalyl alcohol, and belongs to the technical field of chemical synthesis. The synthetic method is characterized by comprising the following reaction steps of: (1), enabling 2,3,5,6-tetrafluoro benzyl alcohol to react with strong base in an insert solvent, to obtain 2,3,5,6-tetrafluoro benzyloxy negative ions; (2), enabling the obtained 2,3,5,6-tetrafluoro benzyloxy negative ions to react with alkylchlorosilane, to obtain 2,3,5,6-tetrafluoro benzyloxy silicane; (3), enabling the obtained 2,3,5,6-tetrafluoro benzyloxy silican to react with an organic lithium reagent, to obtain aryl lithium intermediate; and (4), enabling the obtained aryl lithium intermediate to react with formaldehyde gas, and then hydrolyzing, so as to obtain the 2,3,5,6-tetrafluoro terephthalyl alcohol. The synthetic method has the advantages of easy availability of raw materials, simple operation, high reaction yield and the like. |
