1. Catalyst for the hydrocondensation of carbon monoxide, characterized in that it comprises at least one product obtained by bringing together : (a) at least one complex of formula CuLn in which n is the number of ligands complexing the copper and L is an ionic or covalent ligand, (b) at least one activator of formula M'Rm in which M' is a metal chosen from aluminium, lithium, sodium, magnesium and zinc, m is the valency of the metal M' and R is chosen from the hydrogen atom and hydrocarbon radicals, the molar ration (b)/(a) being between 0.3 and 20, and (c) at least one compound chosen from conjugated dienes, phosphines, amines, arsines and phosphites, the molar ratio (c)/(a) being between 1 and 20. |
