Abstract

An iridium-based solution is prepared by contacting components in a liquid phase containing (a) a carbonylated iridium compound, (b) hydriodic acid, a precursor of such an acid, or mixture thereof, and (c) a solvent; under a total pressure of between 1 and 10 bar at a temperature not greater than the boiling temperature of the solvent under conditions in which the components are brought into contact. The iridium-based solution can be used as a catalyst for carrying out carbonylation, hydroformylation or isomerization reactions.
