Using [η⁶-cyclopentadienyliron]⁺-mediated S(N)Ar chemistry, a series of symmetrical and 2-alkyl tetra-alkyl-p-phenylenediamines have been prepared. The amine/amine^.+ first redox couple has been determined for each member of the series and is influenced by remote steric, electronic, and conformational effects.
