PALLADIUM-CATALYZED ELECTROCHEMICAL CARBONYLATION OF ALKYNES UNDER VERY MILD CONDITIONS

ABSTRACT

Terminal alkynes were carbonylated under very mild conditions to yield acetylenecarboxylates under atmospheric pressure of carbon monoxide at room temperature using palladium(II) catalyst in combination with its anodic recycling at a graphite electrodes.
