PdII catalyst, utilizing a simple and inexpensive amine ligand (TMEDA), allows 2‐alkynoates to be prepared in high yields by an oxidativecarbonylation of terminal alkynes and alcohols. The catalyst system overcomes many of the limitations of previous palladiumcarbonylation catalysts. It has an increased substrate scope, avoids large excesses of alcohol substrate and uses a desirable solvent. The catalyst
