To obtain 2- [ (4-hydroxyphenoxy) methyl] -1,3-benzo dioxene, the synthesis method is as follows:
First take an appropriate amount of raw materials, with phenolic compounds and halogenated alkanes as starting materials. In a suitable reaction vessel, add an appropriate amount of alkali, such as potassium carbonate, etc., to create an alkaline environment and help the reaction proceed. The function of the base is to capture the hydrogen of the phenolic hydroxyl group and form phenoxy negative ions to enhance its nucleophilicity.
The halogenated alkanes are slowly added dropwise to the reaction system containing phenoxy anions. Under this basic condition, the phenoxy anions act as nucleophiles to attack the carbon atoms of the halogenated alkanes and undergo nucleophilic substitution reactions, resulting in the formation of intermediates such as (4-hydroxyphenoxy) halomethane. This reaction requires precise temperature control. Depending on the specific properties of the reactants, it is generally carried out in the range from room temperature to moderate temperature rise to ensure the reaction rate and selectivity.
Then, the resulting intermediates are mixed with catechol and a phase transfer catalyst, such as tetrabutylammonium bromide, is added to enhance the material transfer between the two phases. In a suitable organic solvent, the system is adjusted to alkaline again, so that the phenolic hydroxyl group of catechol and the halogen atom in the (4-hydroxyphenoxy) halomethane undergo nucleophilic substitution reaction. The reaction conditions in this step are quite critical, and factors such as temperature and reaction time have an impact on the yield and purity of the product. Generally speaking, it is necessary to react for several hours under the condition of heating and reflux to fully complete the reaction.
After the reaction is completed, the impurities in the system are removed through post-treatment steps such as extraction, washing, and drying. During extraction, a suitable organic solvent is selected to enrich the product in the organic phase. The washing process can remove residual alkalis, salts and other impurities. Desiccants such as anhydrous sodium sulfate are used for drying to remove residual moisture in the organic phase.
Finally, purified by means of column chromatography or recrystallization, pure 2- [ (4-hydroxyphenoxy) methyl] -1,3 -benzo dioxene products can be obtained. During column chromatography, according to the polarity difference between the product and the impurity, a suitable eluent is selected to separate the product from the impurity. Recrystallization requires the selection of a suitable solvent, and the purpose of purification is achieved by taking advantage of the different solubility of the product and the impurity in the solvent at different temperatures.
