The cross-coupling reaction between aryl halides and aqueous ammonia was efficiently catalyzed by the sulfonato-Cu(salen) complex in water with high yields. A variety of substituted aryl bromides and aryl iodides were found to be applicable to the environmentally benign system. Substituted 1H-benzimidazole could also be easily prepared by coupling aqueous ammonia
