The synthesis of a pool of 1,3-diphenyl-6-(R)pentafulvenes was carried out. Reaction with hydrocarbon radical anions resulted in reductive coupling of the fulvenes to give bridged metallocene ligand precursors. In the case of R groups such as 3-pyridyl, bipyridyl, 4-4-(pyridyl)phenyl, 2- and 3-furyl, the ligands contain ancillary coordinating functionality, important for incorporation of the bridged metallocene unit into supramolecular frameworks. Characterization of the fulvenes and bridged structures was carried out using 1H and 13C NMR, gc/ms, single crystal X-ray, and thermal analytical techniques (TGA, TGA-DTA/DSC). The effect of the pentafulvene structure with differing R groups on the structure of the ansa-ligand precursors as well as on the resulting metal containing compounds will be discussed.
