摘　　要：杯[4]芳烃与过量氯乙酸乙酯反应,得到杯[4]芳烃四酯基衍生物2.化合物2与水合肼反应得到杯[4]四酰肼衍生物3,化合物3进一步与异硫氰酸苯酯反应得到四取代杯[4]芳烃酰胺基硫脲衍生物4.反应处理简便,总产率为71%.新化合物的结构经红外光谱、核磁共振氢谱和质谱表征.阳离子萃取实验表明,化合物4不仅对软硬金属离子均有较好的萃取性能,而且对N a+和A g+有一定的选择性配合能力.By reacting calix[4]arene with ethyl chloroacetate, calix[4]arene tetra-esters derivative 2 was synthesized. Compound 3 was prepared by hydrazinolysls of compound 2 with hydrazlne hydrate. Further reacting compound 3 with phenyl isothiocyanate, tetra-substituted calix[4]arene containing amide and thiourea units was obtained. The synthetic procedures were simple and the total yleld was as high as 71%. The structures of new compounds were characterized by IR,^1H NMR and MS spectra. The extraction experiments showed that compound 4 not only possessed good complexation properties for both soft and hard cations, but also exhibited good complexation selectivity for Na^＋ and Ag^＋.
