Article abstract of DOI:10.1016/0022-328X(88)83116-4

Benzyl- and phenyl-cyclopentadiene have been shown to react with thallium ethoxide in ethanol to give the corresponding benzyl- and phenyl-cyclopentadienylthallium compounds in excellent yield.These reagents are air stable for brief periods, have extended shelf-lives, and have been shown to be superior starting materials for the synthesis of a variety of cyclopentadienylmetal complexes.
