The present invention relates to metal alkylidene complex comprising a 1-aryl-3-alkyl-imidazol-2-ylidene ligand, wherein the aryl group of said 1-aryl-3-alkyl-imidazol-2-ylidene ligand is an aromatic and wherein the alkyl group of said 1-aryl-3-alkyl-imidazol-2-ylidene ligand is selected from the group consisting of a cyclic secondary aliphatic alkyl and a C2-C10-heteroalkyl, and wherein said metal is selected from the group consisting of Pd, Ag, Au, Ir, Rh, Cu, Ni, Mg, Zn, Ti, Pt and Fe, with the provision that the aryl group of said 1-aryl-3-alkyl-imidazol-2-ylidene ligand is other than an ortho-hydroxyaryl group when said metal is Pd and when said cyclic secondary aliphatic alkyl is cyclohexyl.
本发明涉及一种金属烯基化合物,其包括一种1-芳基-3-烷基-咪唑-2-基亚胺配体,其中所述1-芳基-3-烷基-咪唑-2-基亚胺配体的芳基基团是芳香族的,所述1-芳基-3-烷基-咪唑-2-基亚胺配体的烷基基团选自由环二次脂肪烷基和C2-C10-杂原子烷基的群,所述金属选自Pd、Ag、Au、Ir、Rh、Cu、Ni、Mg、Zn、Ti、Pt和Fe的群,但要求当所述金属为Pd且所述环二次脂肪烷基为环己基时,所述1-芳基-3-烷基-咪唑-2-基亚胺配体的芳基基团不是邻位羟基芳基基团。
