Inhaltszusammenfassung
The condensation of thiophene-2-carbaldehyde or N-methyl-pyrroIe-2-carbaldehyde with ferrocenylamine (eta(5)-C5H5)Fe(eta(5)-C5H4NH2) leads to the formation of heterocyclic imine ligands with a ferrocenyl group as the substituent at the imino nitrogen atom. These ligands react with Fe-2(CO)(9) to produce dinuclear cluster compounds of the type [mu(2)-eta(3)-(Fc)N-CH2-C=C-C(H)=C(H)-X]Fe-2(CO)(6) (Fc=(eta(5)-C5H5)Fe(eta(5)-C5H4); X = S, NMe) by activation of a heteroaromatic C-H bond in beta-pos...The condensation of thiophene-2-carbaldehyde or N-methyl-pyrroIe-2-carbaldehyde with ferrocenylamine (eta(5)-C5H5)Fe(eta(5)-C5H4NH2) leads to the formation of heterocyclic imine ligands with a ferrocenyl group as the substituent at the imino nitrogen atom.

The molecular structure of the heterocyclic imine ligands as well as of one of the dinuclear cluster compounds have been determined by X-ray structure analyses.
