Electrochemical behaviour of ferrocenyl-containing acyl thiourea derivatives

Twenty four N-ferrocenoyl-N-aryl(alkyl or ferrocenyl) thiourea derivatives were prepared and ten of them investigated by cyclic voltammetric method in DMF or CH2Cl2 solutions. The compounds exhibit a higher redox potential than ferrocene. Although distant from the redox centre, the substituents on N can influence the redox potential of ferrocenyl via intramolecular hydrogen bonding.
