Disclosed is a process for catalytic hydrogenolysis of p-substituted benzaldehyde-dialkyl-acetals of the general formula <IMAGE> in which R is an alkyl group, an unsubstituted or substituted aryl group or an unsubstituted or substituted aralkyl group, by means of a catalyst system composed of cobalt carbonyl and at least one nitrogen-containing heterocyclic compound, such as pyridine, pyrrole, pyrrolidone or piperidine and a hydrogen/carbon monoxide mixture to give the corresponding p-substituted benzyl alkyl ether derivatives. |
