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