ABSTRACT:
Aromatic aldehydes are more rapidly produced by reacting hydrogen/carbon monoxide admixture with an aromatic halide in the presence of a noble metal-based catalyst, a tertiary nitrogenous base and, if necessary, a noble metal complexing agent, e.g., a phosphine or phosphite, wherein the concentration of said tertiary nitrogenous base, expressed in moles per liter of reaction mixture, is maintained at a value of at least two moles/liter over the course of the reaction.
