Abstract: The compounds of the formula I or Ia (I) (Ia) in which R1 is alkyl, aryl, alkoxy, alkenyl, arylalkyl, alkylaryl, aryloxy, fluoroalkyl, halogenoaryl, alkynyl, trialkylsilyl or a heteroaromatic radical, R2, R3 and R4, in addition to hydrogen, have the meanings given under R1 and R5 is hydrogen, alkyl, fluoroalkyl or alkenyl, can be obtained in a one-stage process by reaction of a compound II with (substituted) cyclopentadiene in the presence of a base. The compounds I and Ia are suitable as ligands for metallocene complexes which are used as catalysts in olefin polymerization.
