摘要
从简单无机硫、硒化合物直接合成冠醚环上含硫、硒杂原子的杯[4]单硫杂冠-5 及杯[4]单硒杂冠-5; 化合物的结构经1H NMR、MS及元素分析确证. 并研究了它们对Na+ , K+ , NH4+ ,Co2+ , Ni2+ , Ag+ 及Hg2+ 的两相萃取性能, 发现其对Ag+ 、Hg2+
The synthesis of calix[4]monothiocrown 5 and calix[4]monoselenocrown 5 with sulfur and selenium incorporating into poly(oxyethylene) chains was described. Their structures were confirmed by 1H NMR, MS and elemental analysis. It was shown that the calixheterocrowns exhibited a high selectivity for Ag +, Hg 2+ compared with Na +, K +, NH 4 +, Co 2+ and Ni 2+ .
