    Abstract: Racemic metallocene complexes (I) are prepared from bridged transition metal phenolate complexes (II) and alkali metal or alkaline earth metal cyclopentadienyl derivatives. Some (I) are new. Preparation of racemic metallocene complexes (I) involves reaction of bridged transition metal phenolate complexes of formula (II) with alkali metal or alkaline earth metal (preferably magnesium) cyclopentadienyl derivatives and optionally subsequently substituting the bridged phenolate ligands.

Unless specified otherwise alkyl moieties have 1-10 C, aryl 6-20 C and cycloalkyl 3-10 C.
