| 摘要 |
The invention relates to N'-substituted N-acylamidine transition metal complexes of the general formula (I), wherein M represents a transition meta l, selected from the group of metals including Ni, Cu, Ru, Rh, Pd, Os, Ir and P t, 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, R2 is a straight-chain or branched, cyclic hydrocarbon group with 1 to 20 carbo n atoms which can be mono or poly-unsaturated, an aromatic group with 3 to 6 chain members, which is linked directly or via a C1 to C6 alkyl or C2 to C6 alkylene group, whereby the mentioned groups can carry one or more substituents. Ar represents C6 to C10 aryl or hetaryl with 5 to 10 ring members, whereby the mentioned groups can be substituted by C1 to C6 alkyl, C1 to C4 halogenalkyl, NR10R11, COOR6, Si(R7)3Si(R7)2R8, OR3 and/or halogen. Th e invention also relates to a method for producing this new class of metal transition complexes and their use as catalysts.
