ABSTRACT:
The invention relates to N′-substituted N-acylamidine transition metal complexes of the general formula (I), wherein M represents a transition metal, selected from the group of metals including Ni, Cu, Ru, Rh, Pd, Os, Ir and Pt, X represents Cl, Br, triflate, methane sulfonate or p-toluol sulfonate, m is 0, 1 or 2, n is 1, 2 or 3 and the radicals have the following meanings: R1, R2is a straight-chain or branched, cyclic hydrocarbon group with 1 to 20 carbon atoms which can be mono or poly-unsaturated, an aromatic group with 3 to 6 chain members, which is linked directly or via a C1to C6alkyl or C2to C6alkylene group, whereby the mentioned groups can carry one or more substituents. Ar represents C6to C10aryl or hetaryl with 5 to 10 ring members, whereby the mentioned groups can be substituted by C1to C6alkyl, C1to C4halogenalkyl, NR10R11, COOR6, Si(R7)3Si(R7)2R8, OR3and/or halogen. The invention also relates to a method for producing this new class of metal transition complexes and their use as catalysts
