中文摘要	A base-free catalyst system Co(acac) 3/BMMImCl was developed for the carbonylation of amines with CO2. 45%–81% isolated yields for N,N′-dialkylureas and 6%–23% isolated yields for N,N-diarylureas were obtained. The catalyst system was recovered and reused without significant loss in activity. In this catalyst system, the base ca talyst and chemical dehydrant were efficiently avoided. Different reaction conditions were also discussed and a postulated mechanism was proposed.
