Abstract: Two novel benzo-15-crown-5 derivatives containing thiocycle(3) and selenacycle(4) have been synthesized in the presence of Na2S·9H2Oor Na2Se2and characterized by elemental analysis and mass, IR, UVand1H NMRspectroscopy.The cation binding abilities and selectivities of parent benzo-15-crown5(1) and its derivatives3 and4 with alkali and heavy metal ions have been evaluated by solvent extraction of aqueous metal picrates.The results obtained indicated that novel selera3cyclopentene[3,4 d]benzo-15-crown-5(4) showed moderate extractability and selectivity for Ag+over any other alkali and heavy metal ions

Key words: Benzo-15-crown-5 derivatives, Synthesis, Extractability, Cation selectivity
