The reaction of dipyrrylmethane with an equimolar mixture of ferrocenecarboxaldehyde and benzaldehyde in dry acetonitrile in the presence of a catalytic amount of trichloroacetic acid leads to the formation of 5-ferrocenyl-15-phenyl-2,8,12,18-tetraethyl-3,7,13,17-tetramethylporphyrin (1) with a yield of 27%. The metallation of 1 with Zn(OAc)2·2H2O and MnCl2·4H2O gives Zn·1 and MnCl·1, respectively. Cyclic voltammograms of 1, Zn·1 and MnCl·1 show reversible one-electron oxidation processes for the oxidation of ferrocene at 0.29, 0.22, and 0.37 V, respectively. Variable temperature 1H NMR spectra of 1 in toluene-d8 show two distinct singlets of equal intensities and line widths for NH protons. From the plot of ln (k/T) versus l/T according to the Eyring equation, gave straight line with ΔG(+) = 51 kJ mol-1. (C) 2000 Elsevier Science Ltd.
