Abstract

Aromatic aldehydes of general formula (I) - (where R1, R2, R3, R4 and R5 may all be hydrogen, halogen, 1-4C alkyl, 1-4C alkoxy or nitro gps) - are prepd from aromatic acid chlorides of formula (II) (substit gps unchanged) by catalytic hydrogenolysis in the presence of a palladium-catalyst and a tert-amine hydrogen acceptor in a suitable solvent. The pptd hydro-chloride forms a homogeneous solid phase with the catalyst during the reaction; both are filtered out and reused following regeneration. (Dwg.0/0)
