Abstract
A regiospecific, catalyzed process for preparing acyl derivatives of aromatic nitrogen-containing heterocyclic compounds in which the keto group is selectively added ortho to the nitrogen atom on the aromatic ring. In the presence of a ruthenium carbonyl compound, carbon monoxide and an olefin, the aromatic heterocyclic compound which has an unsubstituted carbon atom ortho to at least one of the heterocyclic atoms adds the acyl group essentially completely in ortho position.
