Abstract: The synthesis of a series of mixed (bi)pyridyl/(bi)1,3,4-thiadiazolyl ligands, derived from the condensation of 2-mercapto-5-methylthio-1,3,4-thiadiazole or 5-mercapto-5'-methylthio-2,2'-bi-1,3,4-thiadiazole with 2,6-bis(chloromethyl)pyridine or 6,6’-bis(chloromethyl)-2,2’-bipyridine (compounds L1–L4), and of 2,5-dimercapto-1,3,4-thiadiazole or 5,5'-dimercapto-2,2'-di-1,3,4-thiadiazole with picolyl chloride hydrochloride or 6-chloromethyl-6'-methyl-2,2'-bipyridine (compounds L5–L8) in the presence of triethylamine is described. All new compounds have been characterized by FAB (+) spectrometry and NMR spectroscopy. 13C-NMR spectra are crucial to firmly establish the thiol structure of the title ligands.
Keywords: (Bi)pyridyl derivatives; (bi)-1; 3; 4-thiadiazolyl derivatives; (bi)pyridyl/(bi)-1; 3; 4-thiadiazolyl mixed ligands; azathio ligands
