Synthesis and Metal-Ion Extraction Properties ofpara-tert-Butylcalixareneglycine Ester Acetamides

Abstract

Calixareneglycine ester acetamides 4a–c have been synthesized from calixareneacetyl chlorides 5a–c and glycine ethyl ester (6). Their ion‐binding properties have been investigated by liquid‐liquid extraction with radiotracer techniques. The experiments reveal a moderate affinity towards silver(I) ions, which increases with calixarene ring size.
