Abstract: A process for preparing 1,2-diimine compounds of the formula Iwhere R1 and R2 are, independently of one another, alkyl, aryl or metallocenyl radicals, and R3, R4 are, independently of one another, H, alkyl or aryl radicals or R3 and R4 are joined so as to form, with inclusion of the two imine carbon atoms, a 5- to 8-membered ring which may be saturated or unsaturated and may be unsubstituted or substituted by any hydrocarbon radicals. The process involves reacting 1,2-dicarbonyl compounds with primary amines, which have been activated with trialkylaluminum compounds prior to the reaction with the 1,2-dicarbonyl compounds. 1,2-Diimine compounds of the formula I in which R1 and R2 are, independently of one another, metallocenyl radicals can be used to prepare metal complexes which can be used as catalysts in a process for the polymerization of unsaturated compounds.

Abstract: The invention relates to a method for producing 1,2-diimine compounds of general formula (I) in which the symbols have the following meanings: R and R , independent of one another, represent alkyl radicals, aryl radicals or metallocenyl radicals; and R , R , independent of one another, represent H, alkyl radicals or aryl radicals; or R , R form a cyclic radical together so that, including both imine carbon atoms, a 5- to 8-member ring is formed which can be saturated and unsaturated or arbitrarily substituted with hydrocarbon radicals. The inventive compounds are produced by reacting 1,2-dicarbonyl compounds with primary amines, whereby the amines are activated with trialkylaluminum compounds before being reacted with the 1,2-dicarbonyl compounds. The invention also relates to 1,2-diimine compounds of general formula (I), wherein R and R , independent of one another, are metallocenyl radicals. Finally, the invention relates to metal complexes comprised of compounds of formula (I) and to the use of these metal complexes as catalysts in a method for polymerizing unsaturated compounds.
