To prepare [4- (2-hydroxytetradecyloxyphenyl) ] phenyl iodine hexafluoroantimonate, the following ancient method can be used.
First take an appropriate amount of 4-iodophenol and 1,2-oxide tetradecane and place in a clean reactor. Pre-fill the kettle with an organic solvent, such as N, N-dimethylformamide (DMF), as the reaction medium. Add an appropriate amount of alkali, such as potassium carbonate, to promote the reaction. Warm to a suitable temperature, about 80-100 ° C, and continue to stir at this temperature. In this process, the phenolic hydroxyl group of 4-iodophenol reacts with 1,2-epoxytetradecane to form 4- (2-hydroxytetradecyl) iodobenzene.
After the reaction is completed, the solvent in the reaction system is removed by reduced pressure distillation. The resulting crude product is purified by column chromatography to obtain pure 4- (2-hydroxytetradecyl) iodobenzene.
Then, the product is taken and dissolved in a suitable solvent, such as dichloromethane. In this solution, slowly add an appropriate amount of phenylboronic acid and an appropriate amount of catalyst, such as tetrakis (triphenylphosphine) palladium (0), and add an appropriate amount of base, such as sodium carbonate in aqueous solution. Stir the reaction at room temperature to make it arylated to generate [4- (2-hydroxytetradecyloxy phenyl) ] phenyl iodine compound.
The reaction is over, and [4- (2-hydroxytetradecyloxy phenyl) ] phenyl iodine is obtained by conventional separation methods, such as extraction, washing, and drying. Dissolve this product in acetonitrile, add equal moles of silver hexafluoroantimonate, and stir the reaction in the dark for a period of time. After the reaction is completed, the resulting silver halide precipitate is filtered off, and the solvent is removed by reduced pressure distillation to obtain a crude [4- (2-hydroxytetradecyl oxyphenyl) ] phenyl iodine hexafluoroantimonate. Then by recrystallization, a suitable solvent, such as a mixed solvent of acetonitrile and ether, is selected to purify it, and a pure target product can be obtained.
