Abstract

Abstract CpCr(acac)Cl has been prepared by reacting CpCr(THF)Cl 2 with sodium acetylacetonate. Related Cr compounds containing the C 5Me 5 group and ethylacetoacetate have also been studied. Catalysts active for the polymerization of ethylene are obtained by treating these compounds with aluminium alkyls while the title compound reacts with Et 2AlCl or Et 3Al to give [CpCr(μ-Cl)Et] 2.
