ABSTRACT:
A process is provided for the preparation of a juxtanuclear or extranuclear aromatic aldehyde, said process comprising effecting the catalytic reduction of the corresponding acid chloride using hydrogen in the presence of a palladium catalyst and a tertiary amide. The use of the tertiary amide increases the selectivity, activity and working life of the catalyst as compared with conventional processes and renders the use of catalyst regulators such as quinoline or sulphur-containing compounds unnecessary.
