摘要：
Three new oxathiacrown ethers 1, 2 and 3 containing a sulfoxide group were synthesized in a simple way. Conductometric titration studies in pure acetonitrile were employed to invistigate their binding affinities towards Ag+, Cu2+, Pb2+, Cd2+, Zn2+, Co2+, Ni2+, Cr3+ and Hg2+. They were found to be selective for Ag+ and Cu2+ over the other metals investigated. Ligand 1 has the highest selectivity towards Ag+. The structure of compound 3 was confirmed by X-ray crystallography.
