Reaction of in situ generated lithium fluorenide salts with cobalt chloride results in formation of the corresponding bifluorenes. The scope of fluorenes that can be coupled include those containing substituents amenable to polymerization for application to poly(bifluorene) synthesis and alkyl substituted fluorenes for use in the preparation of bimetallic transition metal complexes.
