Abstract

A process for preparing an arylacetaldehyde by reacting the corresponding arylmethyl halide with carbon monoxide and hydrogen in the presence of a cobalt compound and a basic reagent in a liquid medium, characterized in that the basic reagent is an alkali metal compound and the liquid medium is a solvent system chosen from nitriles and their mixtures with hydrocarbons, whereby the arylacetaldehyde can be produced in a good yield by the use of a small amount of the cobalt compound as the catalyst.
