摘要:
The compounds of the formula I or Ia ##STR1## in which R.sup.1 is alkyl, aryl, alkoxy, alkenyl, arylalkyl, alkylaryl, aryloxy, fluoroalkyl, halogenoaryl, alkynyl, trialkylsilyl or a heteroaromatic radical,R.sup.2, R.sup.3 and R.sup.4, in addition to hydrogen, have the meanings given under R.sup.1 andR.sup.5 is hydrogen, alkyl, fluoroalkyl or alkenyl, can be obtained in a one-stage process by reaction of a compound II ##STR2## 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.
