摘要 |
The invention relates to a process for the preparation of 5-arylnicotinaldehydes by reduction of the corresponding 5-arylnicotinic acids by catalytic hydrogenation in the presence of carboxylic anhydrides in which the catalyst used is a palladium/ligand complex, characterized in that the molar ratio between palladium and ligand is from 1:5 to 1:15 in the case of monodentate ligands and from 1:2.5 to 1:7.5 in the case of bidentate ligands. |
