Synthesis,Metal Ion Complexation Properties,and Electrochemical Behavior of Ferrocenyl Thioacetal Crown Compounds

Abstract

Condensation of ferrocenecarboxyaldehyde with dithiols under Lewis acid catalysis produces ferrocenyl thioacetal crown compounds in good to excellent yields. Complexation behavior of several ferrocenyl thioacetal crown compounds toward alkali metal cations, Ag(I), Tl(I), Cu(II), Pb(II) and Zn(II) is assessed by picrate extractions from aqueous solutions into chloroform. Electrochemical behavior of several ferrocenyl thioacetal crown compounds in the absence and presence of sodium ions is investigated by cyclic voltammetry.
