摘　　要：合成了下沿带磺酸基的两种新型水溶性杯芳烃衍生物4和5,用红外、核磁与质谱表征确证了它们的结构与构象。以氯化苄和硫氰酸钾的亲核取代反应为催化体系研究了它们的催化性能,结果表明它们均具有很好的水相催化能力,最佳的催化条件为摩尔比n(对硝基氯化苄)∶n(硫氰酸钾)∶n(催化剂)=1∶3∶0.009,80℃下反应3 h,硫氰酸苄酯产率可达近90%。Two novel water soluble calix[4]arene derivatives 4 and 5 with sulfonic acid groups on lower rims were synthesized.Their structures and conformations were characterized by IR,1H NMR and ESI-MS.Using the nucleophilic substitution of reacting benzyl chloride with potassium thiocyanate as catalytic system,compounds 4 and 5 exhibited excellent catalytic properties.The optimized catalytic condition was n（benzyl chloride）：n（potassium thiocyanate）：n（catalyst）=1：3：0.009 at 80 ℃ for 3 h.The yield was as high as 90%.
