    摘要： Bisimine compounds of the formula (I) where the symbols have the following meanings: A is a nonmetal selected from among N, S, O and P, R1 is a radical of the formula NR5R6, R2 is a radical of the formula NR5R6 or NR7R8, alkyl, aryl or cycloalkyl, R5 and R6 together with the N atom form a 5-, 6- or 7-membered ring in which one or more of the —CH— or —CH2— groups may be replaced by suitable heteroatom groups and which may be saturated or unsaturated and unsubstituted or substituted or be fused with further carbacyclic or heterocarbacyclic 5- or 6-membered rings which may in turn be saturated or unsaturated and substituted or unsubstituted, and R7 and R8 are, independently of one another, alkyl, aryl or cycloalkyl radicals, and R3, R4 are, independently of one another, H or alkyl, aryl or cycloalkyl radicals, and n is 1 or 2, are used to prepare bisimidinato complexes which can be used in the polymerization of unsaturated compounds.

    摘要： An organometallic compound of the formula I where M1 is selected from among Fe, Ru and Os and M2 is selected from among the transition metals of groups IV to VI of the Periodic Table, which can be prepared by reacting an organometallic compound of the formula II with a transition metal compound of the formula III, M2L1L2(L3)x+1  III where the variables are as defined above and the organometallic compound of the formula II can, if desired, be doubly deproteinated beforehand, can be used as part of a catalyst system for the polymerization or copolymerization of olefins. This catalyst system comprises one or more organometallic compounds of the formula I and at least one activator. The compound of the formula I can also be used to produce a solid catalyst comprising at least one organometallic compound of the formula I, at least one activator and a solid support by impregnating a support material with one or more organometallic compounds of the formula I and at least one activator. This solid catalyst can be used in a process for the polymerization or copolymerization of olefins in bulk, in suspension or in the gas phase.
