It was shown that cis-2,4-bis(2,4,6-tri-tert-butylphenyl)-1,2,4-thiadiphosphetane 2,4-disulfide (1) acts as an excellent Ag+-selective extractant. Two-phase solvent-extraction and spectral examination with 1H and 31P NMR established that 1 forms a 1:1 complex with Ag+ using the P(=S)-S-P(=S) linkage designed in the rigid four-membered ring.
