Thiacrown Molecular Basket with High Extracting Selectivity towards Ag⁺

Department of Chemistry, Wuhan University, Wuhan 430072

Received Date: 30 May 2005

By bridging 1, 3:4, 6-bis(3, 6-dihydroxy-1, 2-xylylene)tetrahydro-3a, 6a-diphenyl imidazo[4, 5]-imidazole-2, 5(1H, 3H)-dione 1 with S(CH₂CH₂OCOCH₂Cl)₂, thiacrown molecular basket 2c was prepared for the first time. It was found that the compound exhibited very poor affinity towards alkali metal ions but high extracting selectivity towards silver ion.
