Abstract:
The invention relates to a process for the preparation of a compound of the formula XI (XI) wherein preferably M1 is zirconium, the radicals R1 are alkyl, the radicals R2 are halogen or alkyl, R3 is dimethylsilyl or ethylene and n is 2-18, wherein a compound of the formula II (II) is reacted with an alkali metal or alkaline earth metal salt of a malonic ester and then with an alkyl halide, the reaction product is converted by decarboxylation into the corresponding lactone, which is further reacted by known methods to give the compound XI. The compounds of the formula XI, some of which are novel, can advantageously be used as catalysts for olefin polymerization.
