摘　　要：The ligand free coupling reaction of phenyl urea with different functionalized aryl halides in the presence of air stable Cu_2O and t-BuOK 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 ligand.The ligand free coupling reaction of phenyl urea with different functionalized aryl halides in the presence of air stable Cu_2O and t-BuOK 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 ligand.
