Synthesis and Characterization of Biferrocene Schiff Base Complexes

摘要

A series of mono- or di- substituted biferrocene-containing Schiff base complexes Fc-X-Fc and Fc-X2-Fc (X=-CH=N-C6H4-N=CH-, -CH=N-C6H4-C6H4-N-=CH- and -CH=N-C6H4-CH2-C6H4-N=CH-) have been synthesized by means of condensation of formylferrocenes with amines under improved conditions. The complexes were characterised on the basis of their elemental analyses and spectral data (IR, UV,1H NMR, magnetic moment and MS). The complexes are oxidized by iodine in absolute ethanol to give mixed valence compounds, which showed paramagnetic properties.
