An efficient electrochemical synthesis of 5-methylene-1,3-oxazolidin-2-ones (2a−h) from acetylenic amines (1a−h) and carbon dioxide has been achieved by direct electrolysis of solution of MeCN and Et4NPF6 containing the amine, with subsequent CO2 bubbling and heating. The yields vary from good to excellent, the conditions are mild, and the use of toxic and harmful chemicals and catalysts is avoided
