Abstract
A novel synthesis of several dialkylureas by electrocatalytical carbonylati on of aliphatic amines was investigated at 30 degreesC and atmospheric pres sure in the presence of Pd(II) and Cu(II) cocatalyst., This catalyst system was very effective for the carbonylation of primary mono-amines. Furthermo re, the phenomenon of the non-Faradic electrochemical modification of catal ytic activity was observed in this homogeneous reaction system and the curr ent efficiency for dialkylurea formation reached 401%.
