Substituted pentadiene compound according to formula (I) or (II), where R<1-2> are substituents and at least one R<2> substituent has the form RDR'n, where D is a hetero atom from group 15 or 16 of the Periodic System of the Elements, R' is a substituent on the hetero atom and R is a linking group. The invention also relates to a process for the synthesis of a substituted pentadiene compound. Metal complexes in which at least one of these cyclopentadiene compounds is present as a ligand are useful as catalysts for the polymerisation of alpha-olefins. |
