Abstract
The 2-(8’-chlorotriethyleneglycolmercapto)imidazo[4,5-b]pyridine 2 is prepared by reaction between bis chlorotriethyleneglycol and 2H-imidazo[4,5-b]pyridine-2-thione 1. Compound 2 showed selectivity towards transition metals such as (Zn2+, Cu2+, Cd2+). The sites of complexation are localized by vibrational spectroscopy, the formation constants of the different complexes are determined by UV spectrophotometry.
