Abstract

El cometido de la invención era encontrar un procedimiento para la producción selectiva de complejos de metaloceno racémico, prácticamente libre de meso - isómero (exactitud de medición por RMN). Otro cometido era encontrar complejos de metaloceno racémico, que se o bien se puedan utilizar directamente como o en catalizadores, con preferencia para la polimerización de olefina o que se puedan utilizar después de modificación, por ejemplo después de la substitución de un "ligando auxiliar", como o en catalizadores, presumiblemente para la polimerización de olefina, o que se puedan utilizar como reactivos o catalizadores en la síntesis estereoselectiva. De acuerdo con ello, se encontraron el procedimiento definido en las reivindicaciones de patente, los complejos de metaloceno racémico III, así como su utilización como catalizadores o en catalizadores para la polimerización de compuestos insaturados olefínicamente o como reactivos o catalizadores en la síntesis estereoselectiva.
