    • The object of the invention resides in the development of an improved process for synthesizing metallocene compounds useful as olefin polymerization catalysts.A new process for synthesizing metallocene compounds of formulae (IV) and (IV') comprises a reaction of formula (I) with formula (II) or (II') to afford formula (III) or (III'), and then a reaction of a halogenating agent.In formulae (IV) and (IV') described below, M.sup.1 is a group IV transition-metal atom, L.sup.1 and L.sup.2 can be each other identical or different and are substituted or unsubstituted cyclopentadienyl, substituted or unsubstituted indenyl or substituted or unsubstituted fluorenyl groups, B is a hydrocarbon having 1-20 carbon atoms, silylene having 1-20 carbon atoms, oligosilylene or germylene groups, binding to L.sup.1 and L.sup.2, Y can be identical or different and is each independently of one another a halogen atom. Further, M.sup.1 can be coordinated with an ether or an amine at any coordination number. ##STR1##
