Abstract
A number of process steps are provided that can be combined to produce bridged cyclopentadienyl-fluorenyl metallocenes. The process steps include production of a cyclopentadiene compound from dicyclopentadiene; production and recovery of a fulvene compound using the cyclopentadiene compound; production of a raw metallocene product using the fulvene compound; and recovery of the pure metallocene from the raw product.
