Super-crowded metallocenes: The reaction of diferrocenylacetylene and 1,4-diferrocenylbuta-1,3-diyne with Group 4 metallocene compounds yields attractive multiferrocenyl complexes. Depending on the metal, different products were obtained by complexation, coupling, or CC bond cleavage of the ligand (see scheme). Their electrochemical properties were studied in detail. The oxidation of the metallacycle induces decomposition of the complexes.
