摘要

Abstract N, N-Diarylureas were obtained in good yields from nitroarenes and aminoarenes at 140 C under carbon monoxide (initial 60 kg cm− 2) in the presence of a catalytic amount of dichlorobis (triphenylphosphine) platinum (II), the yields of N, N′-diphenylurea, N, N′- bis (4-methylphenyl) urea, and N, N′-bis (4-chlorophenyl) urea were 65, 67 and 61%, respectively. Benzimidazole derivatives were obtained by the intramolecular cyclization ...
