Using [eta(6)-cyclopentadienyliron](+)-mediated SNAr chemistry, a seri
es of symmetrical and 2-alkyl tetra-alkyl-p-phenylenediamines have bee
n prepared. The amine/amine(.+) first redox couple has been determined
for each member of the series and is influenced by remote steric, ele
ctronic, and conformational effects. (C) 1997 Elsevier Science Ltd.
