A catalyst composition comprising a catalyst and an activating cocatalyst is claimed. The catalyst has the formula LMX1X2, wherein X1 and X2 are independently halide, hydride, triflate, acetate, trifluroacetate, tris perfluorotetraphenyl borate, tetrafluoroborate, straight chain or branched alkyl or alkoxy of 1-12 carbon atoms, cycloalkyl or cycloalkoxy of 3-12 carbon atoms, or aryl; M is Cu, Ag, or Au; L is a nitrogen-containing bidentate ligand. The nitrogen in L is preferably contained in 5 or 6-membered heterocyclic rings, two of which are bonded to a hydrocarbyl bridging group. The activating cocatalyst is generally an aluminum compound or other Lewis acid.
L'invention porte sur une composition comprenant un catalyseur et un cocatalyseur d'activation. Le catalyseur a la formule LMX1X2 dans laquelle X1 et X2 représentent, indépendamment, halogénure, hydrure, triflate, acétate, trifluoroacétate, tris perfluorotétraphényl borate, tétrafluoroborate, alkyle à chaîne droite ou ramifiée ou alcoxy comprenant 1 à 12 atomes de carbone, cycloalkyle ou cycloalcoxy comprenant 3 à 12 atomes de carbone ou aryle. M représente Cu, Ag ou Au. L représente un ligand bidenté renfermant azote. L'azote en L est de préférence contenu dans des noyaux hétérocycliques à 5 ou 6 éléments dont deux sont liés à un groupe de pontage hydrocarbyle. Le cocatalyseur d'activation est en général un composé d'aluminium ou un acide de Lewis.
