Synthesis and Characterisation of Some New Ferrocenyl- and Ferrocenylalkynyl-[60]Fullerene Compounds

We report the synthesis and characterisation of a series of ferrocenylfullerene compounds, and some new ferrocene derivatives required as intermediates. The new fullerene species are Fc-[60]fullerene, (8); Fc-C[dbnd]C-[60]fullerene, (10); Fc-C[dbnd]C-C[dbnd]C-[60]fullerene, (12); and (η-C5H4SiBu3)Fe(η-C5H4)-[60]fullerene, (14).
