The present invention is directed to a process for the carbonylation of an arylene to an arylaldehyde (e.g., toluene to tolualdehyde) in the presence of a solid acid catalyst. The process for making tolualdehyde comprises carbonylating toluene in the presence of either carbon monoxide or a source of carbon monoxide and in contact with a solid acid catalyst. The reaction is carried out at a temperature ranging from -40.degree. to 200.degree. C., and at a pressure ranging from 20-4000 psig.
