  • Abstract: Abstract Using CO2to replace phosgene or CO as the C1 synthon, we successfully achieved the one-pot electrochemical synthesis of 1, 3, 4-oxadiazol-2(3 H )-one derivatives via a three-component coupling reaction of CO2with aryl hydrazines and paraformaldehyde in an undivided cell. With NaI as the electro-catalyst and t -BuOK as the base, this electrochemical process could be smoothly performed to afford the target products in good to high yields at room temperature. Graphical abstract Image 2 Highlights Using CO2to replace toxic phosgene or CO as the C1 synthon. The electrochemical conversion of CO2with aryl hydrazines and paraformaldehyde into 1, 3, 4-oxadiazol-2(3 H )-one derivatives in one step. The present work provides a new route to synthesize 1, 3, 4-oxadiazol-2(3 H )-one derivatives and utilize CO2. I2and base electrogenerated in situ play a significant role in the transformation.
