摘要

New transition metal complexes (I) of nickel, palladium and platinum have a ligand with electron-depleted olefinic double bond(s) and a monodentate carbene ligand comprising a 1,3-di-substituted imidazol(in)-ylidene compound with (cyclo)alkyl) and/or (hetero)aryl substituents. New transition metal complexes (I) of nickel, palladium and platinum are of the formula: [Image] M : Ni, Pd or Pt; L 1a ligand with electron-depleted olefinic double bond(s); L 2a monodentate carbene ligand of 1,3-di-substituted imidazol(in)-ylidene type. The full definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are also included for the following: (1) bridged transition metal complexes of formula (Ia) or (Ib), where the bridging group L 1 is selected so that it has another co-ordination position for a Ni, Pt or Ni atom: (2) preparation of (I).
