Abstract

The synthesis of novel diamide derivatives of calix[4]arene by aminolysis of calix[4]arene diesters was reported. The 1H and 13C NMR, data showed that the synthesized compounds exist in the cone conformation. The complexation properties of these calix[4]arenes have been studied towards [image omitted] anions and it has been found that the protonated alkyl ammonium forms of calix[4]arene diamide derivatives (5,11,17,23-tetra-tert-butyl-25,27- (diethylpiperidineacetamido)26,28-dihydroxy-calix[4]arene 3 and 25,27-(diethyl-piperidineacetamido)26,28-dihydroxycalix[4]arene 4) are effective extractants for transferring [image omitted] anions.
