Abstract:
A metal complex obtainable from a metal precursor of a metal of the 6th-10th groups of the Periodic Table in the oxidation state 0 or +2 and a ligand of the formula I, whereR1, R2 and R4 are, independently of one another: hydrogen, C1-C12-alkyl, C1-C12-alkyl bearing one or more identical or different C1-C12-alkyl groups, halogens, C1-C12-alkoxy groups or C1-C12-thioether groups as substituents, C7-C20-arylalkyl, C2-C12-alkenyl, C3-C12-cycloalkyl, C3-C12-cycloalkyl bearing one or more identical or different C1-C12-alkyl groups, halogens, C1-C12-alkoxy groups or C1-C12-thioether groups as substituents, C6-C14-aryl, C6-C14-aryl bearing one or more identical or different C1-C12-alkyl groups, halogens, monohalogenated or polyhalogenated C1-C12-alkyl groups, C1-C12-alkoxy groups, silyloxy groups OSiR7R8R9, amino groups NR10R11 or C1-C12-thioether groups as substituents, C1-C12-alkoxy groups, C6-C14-aryloxy groups, C1-C12-thioether groups, silyloxy groups OSiR7R8R9, halogens or amino groups NR10R11; R3 is selected from among the following groups: &agr;-branched C3-C12-alkyl groups, C1-C12-alkyl bearing one or more identical or different C1-C12-alkyl groups, halogens, C1-C12-alkoxy groups or C1-C12-thioether groups as substituents in the &agr; position, C7-C20-arylalkyl, C2-C10-alkenyl, C3-C10-alkenylalkyl having at least one double bond, where at least one Câ€”C double bond is conjugated with the aromatic, C3-C12-cycloalkyl, C6-C14-aryl, C6-C14-aryl bearing one or more identical or different C1-C12-alkyl groups, halogens, monohalogenated or polyhalogenated C1-C12-alkyl groups, C1-C12-alkoxy groups, silyloxy groups OSiR7R8R9, amino groups NR10R11 or C1-C12-thioether groups as substituents, C1-C12-alkoxy groups, C6-C14-aryloxy groups, C1-C12-thioether groups, silyloxy groups OSiR7R8R9, halogens and amino groups NR10R11, where in each case adjacent radicals R1 to R4 may together form a 5- to 8-membered ring; R5 and R6 are selected independently from among &agr;-branched C3-C12-alkyl groups, C3-C12-cycloalkyl groups, C3-C12-cycloalkyl groups bearing one or more identical or different C1-C12-alkyl groups, halogens, monohalogenated or polyhalogenated C1-C12-alkyl groups, C1-C12-alkoxy groups, silyloxy groups OSiR7R8R9, amino groups NR10R11 or C1-C12-thioether groups as substituents, X is oxygen, sulfur, selenium, Nâ€”R12, Pâ€”R12 or AsR12, Y is hydrogen or an alkali metal cation, a C1-C18-alkylacyl anion, a C6-C14-arylacyl anion or SiR7R8R9, R7 to R12 are selected independently from among hydrogen, branched or unbranched C1-C6-alkyl groups, benzyl radicals and C6-C14-aryl groups, where in each case two adjacent radicals R7 and R8 or R10 and R11 may together form a saturated or unsaturated 5- to 8-membered ring.
