A concise method for the preparation of carbodiimides from thioureas using di-tert-butyl dicarbonate [(Boc)2O] as the dehydrosulfurizative reagent has been developed. Using DMAP as the catalyst, a variety of symmetric and asymmetric 1,3-diaryl thioureas were converted into the corresponding carbodiimides efficiently in a short time.
使用用于从硫脲制备碳化二亚胺的简明方法二-叔丁基二碳酸酯[(BOC)2 O]作为dehydrosulfurizative试剂已经研制成功。使用DMAP作为催化剂,可以在短时间内将各种对称和不对称的1,3-二芳基硫脲有效地转化为相应的碳二亚胺。
