The coupling reaction of phenylurea with different functionalized aryl halides in the presence of air stable Cul, N,N-dimethylethylenediamine as a ligand, and K₃PO₄ as a base gives symmetrical and unsymmetrical diarylureas in relatively high yields.This method is milder than the palladium catalyzed arylation and avoids the use of toxic phosphine ligands.
