摘　　要：目的研究快速合成对甲氧基苯乙烯基染料的合成方法。方法在微波促进下,以2-烷基或4-烷基取代的杂环碱或杂环季铵盐和对甲氧基苯甲醛为原料,在催化剂作用下合成一系列对甲氧基苯乙烯基染料,并用元素分析,1HNMR,MS,IR,UV-vis确证产物的结构。结果合成所需时间短、产率高。结论提供了一种快速合成对甲氧基苯乙烯基染料的有效方法。Aim To investigate a novel rapid synthetic method of p-methoxy styryl dyes.Methods A series of p-methoxy styryl dyes were synthesized by the reaction of bases or quaternary salts of heterocyclic 2- or 4-alkylcompounds with p-methoxy aldehyde in the presence of catalyst under microwave irradiation. The products were identified by ~1H NMR, MS, IR, UV-vis and elemental analysis. Results The method was fast, efficient. Conclusion A novel convenient synthetic method of p-methoxy styryl dyes was provided.
