Palladium-catalyzedcarbonylation of 2-haloaniline in the presence of terminal acetylenes under proper conditions (20 Kgcm−2 of CO at 120 °C) gave a variety of 2-substituted 1,4-dihydro-4-oxo-quinolines in good yields.

Synthesis of 2-substituted chromones and quinolones has been performed by a Pd-catalyzed carbonylation of o-iodophenols or o-iodoanilines in the presence of terminalacetylenes in a high yield through coupling of halides and acetylenes followed by cyclization as a one-pot reaction.
