Abstract

Se trata de la preparación de complejos de coordinación de titanio y de zirconio, que poseen un solo ligando cíclico deslocalizado, O-ligado en el queel metal de dicho complejo tiene número de oxidación formal + 2, haciendo reaccionar con excelente rendimiento y pureza, haluros de titanio o de zirconiocuyo estado de oxidación, está expresado por el número de oxidación +3 ó +4 con un reactivo de n-alquilo de Grignard. Se proponen también los complejos decoordinación obtenidos, de aplicación como catalizadores en la polimerización de alfa-olefinas.
