Abstract
The synthesis of unsymmetrical ureas (N-aryl-N′-pyridylurea and N,N′-bipyridylurea) from aryl- or pyridyl carboxamides and aminopyridines in the presence of PhI(OAc)2 has been reported. The formation of pyridylisocyanates from their corresponding carboxamides via Hofmann rearrangement is confirmed.
