Synthesis method of 4-bromophenyl allyl ether

The invention discloses a synthesis method of 4-bromophenyl allyl ether. In the synthesis method, sodium bromide, anhydrous potassium carbonate, P-bromophenol, chloropropene, Nb2O5, K4Nb6O17, and thiourea are used as main raw materials; and P-bromophenol and chloropropene are subjected to substitution reaction under the action of a catalyst Bi2OS2/Nb6O17-NH3. Compared with a conventional synthesismethod, in the method, a two-dimensional laminar composite catalyst is used in a multi-phase reaction system, so that the difficulty of the separation of the product catalyst and a problem of low yield caused by multiple side reactions are avoided, and further the yield of products is greatly increased and the purity of the products is greatly improved. 本发明公开了种对溴苯基烯丙基醚的合成方法，溴化钠、无水碳酸钾、对溴苯酚、氯丙烯、NbO、KNbO和硫脲为主要原料，本发明的合成工艺采用对溴苯酚和氯丙烯在催化剂BiOS/NbO-NH的作用下经过取代反应得对溴苯基烯丙基醚，相较于传统的合成方法，多相反应体系使用二维层状复合催化剂避免了产物催化剂分离困难，副反应较多带来的收率低下的问题，从而使得产物的产率和纯度得到大幅提高。
