Abstract
Abstract This invention relates to the production of aldehydes by the addition of carbon monoxide and hydrogen to olefinically unsaturated compounds in the presence of a complex catalyst comprising cobalt carbonyl and a porphyrin promoter ligand. This process can be carried out under relatively mild conditions of temperature and pressure.
