Copper-catalyzed arylation of phenylurea using KF/Al2O3
A mild and efficient method for the copper-catalyzed arylation of phenylurea is described.
The coupling reaction of phenylurea with different functionalized aryl iodides in the presence
of air stable CuI, N, N′-dibenzylethylenediamine as a ligand, and KF/Al2O3 as a base
gives symmetrical and unsymmetrical diarylureas in relatively high yields.
