The preparation and reaction chemistry of homodinuclear fulvalene metal carbonyl complexes is described. Their study led to the development of the first controlled approach to heterodinuclear derivatives. Unique reactivity has been observed for these complexes. A second, more efficient synthetic strategy was developed that utilizes a cyclopentadienyl-substituted cyclopentenone as a precursor to fulvalene, allowing for the selective, step-wise complexation of transition metals. 1.
