Anovel synthesis of several dialkylureas by indirect electrocatalytical carbonylation of corresponding aliphatic amines was carried out at 50℃and atmospheric pressure with an electrochemically regenerable palladium(Ⅱ) as catalyst and copper(Ⅱ ) acetate as cocatalyst with excellent conversion and selectivity. The results show that the main products are dialkylureas for the mono- aliphatic amines and isocyanates for the diamines. Solvent has a strong impact on the selectivity.
