Anion recognition by 1,3-benzenedisulfonamide derivatives bearing phenolic hydroxy groups in MeCN-d3

The halide anion recognition by 1,3-benzenedisulfonamides derived from 2-aminophenols was studied by H-1 NMR titrations in MeCN-d(3). The results demonstrated that the receptors achieved high recognition ability with chloride anion.
