Abstract

METODO PARA PREPARAR COMPLEJOS DE TITANIO Y ZIRCONIO CON UN GRUPO LIGANDO UNICO, CICLICO, DESLOCALIZADO, DE ENLACE {PI} Y EN DONDE EL METAL DE DICHOS COMPLEJOS SE ENCUENTRA EN ESTADO DE OXIDACION FORMAL +2. ESTE METODO DE PREPARACION DE ALTO RENDIMIENTO Y PUREZA CONSISTE EN LA REACCION DE HALUROS DE TITANIO Y ZIRCONIO EN ESTADO DE OXIDACION +3 O +4 CON UN REACTIVO N-ALQUIL DE GRIGNARD. LOS COMPLEJOS SE UTILIZAN COMO COMPONENTES CATALIZADORES DE LA POLIMERIZACION DE {AL} - OLEFINA.
