以三种烯丙醇为起始原料 ,经溴代生成烯丙基溴 ,然后与无水苯亚磺酸钠发生亲核取代反应生成烯丙基砜。烯丙基溴与烯丙基砜在相转移催化下的偶联反应也可合成新的烯丙基砜。作者用这两种方法合成了六种烯丙基砜。初步探讨了反应温度 ,催化剂等对反应的影响。产物结构经IR ,1 HNMR等波谱分析确证。 The three allyl alcohol as the starting material, brominated to generate allyl bromide, and then anhydrous sodium sulfinate sodium nucleophilic substitution reaction allyl sulfone. Coupling of allyl bromide with allyl sulfone under phase transfer catalysis can also synthesize new allyl sulfones. The authors synthesized six allyl sulfones using these two methods. The effects of reaction temperature and catalyst on the reaction were discussed preliminarily. The product structure was confirmed by IR, 1 H NMR and other spectroscopic analysis.
