Abstract

Process for preparing halide metallocene compounds comprising the step of reacting the dialkyl derivative with a halogenating agent of formula R3xTLw wherein: L is chlorine, iodine or bromine; R3 is hydrogen or a hydrocarbon group; T is a metal of groups 2-14 of the periodic table of the elements; and x is ≧1 so that x+w is equal to the oxidation state of the metal T.
