Abstract
The present work aims at the synthesis of γ-propylsilatrane, possessing 2,5-dimercapto-1,3,4-thiadiazole (H2dmtd) moiety tethered to γ- position of propyl chain derived from γ-chloropropylsilatrane via nucleophilic substitution of chloro group with monoanionic Hdmtd−. The linkage of 2,5-dimercapto-1,3,4-thiadiazole with γ-methylene carbon of propyl chain through N atom was confirmed from spectroscopic studies (1H and 13C NMR) elemental analyses, mass spectrometry and thermogravimetric analyses. UV-Vis spectroscopy, coupled with cyclic voltammetry was used to investigate the receptor action of the silatrane. The successful recognition ability of the synthesized molecule towards acetate, thioaceate and lead ions can be attributed to the presence of N-H and C=S system.
