The article comprises synthesis of calyx[4]-oxa-crown, and calix[4]-thia-crown compounds containing nitrile groups ( 3a, 3b ) and amino groups ( 4a, 4b ) and their corresponding oxime derivatives ( 5a, 5b ) and liquid-liquid extraction studies of these compounds. The oxime derivatives of compounds ( 5a, 5b ) have been synthesized by reacting of di-n-butylamino derivatives of calix[4]-oxa-crown, and calix[4]-thia-crown compounds ( 4a, 4b ) with amphi-chloroglyoxime in methanol-THF. Their cation and anion transfer studies were performed by using liquid-liquid extraction procedure. It has been concluded from the observations that the compound 3a shows a good extraction behavior toward Na + ion in the presence of other metal cations. Whereas, its oxime derivatives transfers all of the metal cations used in the liquid-liquid extraction studies.
