Process For The Preparation Of Aromatic Aldehydes

The present invention is aimed at a process for the preparation of (hetero)aromatic aldehydes. The aldehydes are obtained from corresponding Hal'-substituted (hetero)aromatics by palladium-catalysed reductive carbonylation in the presence of a specific monodentate phosphane-based ligand system.
