Abstract: 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 1HNMR, MS and elemental analysis. It was shown that the calix-heterocrowns exhibited a high selectivity for Ag+, Hg2+compared with Na+, K+, NH4+, Co2+and Ni2+.

Key words: Calixcrown, Extraction, Sulfur, Selenium
