A NEW SYNTHESIS OF CYCLIC UREAS FROM AROMATIC DIAMINES BY SELENIUM-ASSISTED CARBONYLATION WITH CARBON MONOXIDE

Article abstract of DOI:10.1016/S0040-4039(00)84710-3

Aromatic cyclic ureas have been synthesized in good yields from o-amino or o-aminoalkyl substituted aromatic amines by the reaction with carbon monoxide using selenium.
