Abstract

Abstract: A simple and efficient strategy of constructing ferrocene-based thioether ligands through metal-free reductive coupling of thiols with N -tosylhydrazones bearing a ferrocenyl group has been developed. This method features metal-free, good functional group tolerance, and readily available starting materials. Moreover, the compound3k as a novel chemosensor has shown excellent recognition towards Hg 2+ ion via optical and electrochemical signals. Quantification of the absorption titration analysis shows that the detection limit was 9.56×10 −7 M for3k -Hg 2+ . Graphical abstract:
