摘要
将研制得的季鏻盐型高聚物相转移催化剂用于橙花素(即β-萘乙醚)的催化合成。研究结果表明,在β-萘酚∶溴乙烷为1∶1.3(摩尔比),通N2保护,反应温度为75℃,反应时间为5 h的条件下,可获得81.7%的收率。此法具有操作简便、反应温和、催化剂能重复使用、效果良好的优点。
The phase transfer catalyst of quaternary phosphine salt polysterene- supported was prepared. It was used as a catalyst to synthesize β-naphthyl ethyl. The results showed that under the conditions ofβ-naphthyl alcohol and monobromethane in the mole ratio of 1:1.3,N2 protection,reaction temperature of 75℃and reaction time of 5h, the yield was 81.7%. The method has the advantages of easy operation,mild reaction,good yield. The catalyst could be reused.
