RuCl 2 (PPh 3 ) 3 catalyzed condensation of 1,1'-ferrocenedimethanol with primary amines afforded N-alkyl- or N-aryl-2-aza-[3]-ferrocenophanes which were characterized by 1 H and 1 3 C NMR spectra. X-ray crystallography of N-(4-butylphenyl)-2-aza-[3]-ferrocenophane unequivocally revealed its mononuclear structure. The N-C (aryl) bond distance is shorter than the N-CH 2 single bond due to extension of π-conjugation of the aromatic ring to the nitrogen atom. N-Hexyl-2-aza-[3]-ferrocenophane reacts with methyl iodide to give the N-methylated product which was characterized by NMR spectroscopy and X-ray crystallography. N-Aryl-2-aza-[3]-ferrocenophanes exhibited reversible redox between ferrocene and ferrocenium cations and an irreversible oxidation peak at a higher oxidation potential.
