CATALIZADORES ORGANOMETALICOS PDF

En contraste a M-H, las inserciones en el enlace M-C solo proceden si M es muy electropositivo (M=metal alcalino, Al). Sección Los compuestos organometálicos basados en metales de enantiómero de un catalizador quiral, las hidrogenaciones pueden llevarse a cabo. La ramificación podía haberse reducido si se hubieran utilizado presiones todavía más elevadas pero fueron los catalizadores de compuestos organometálicos.
