摘要：
An efficient method for the Lossen rearrangement that uses 2,4,6-trichloro-1,3,5-triazine (TCT) as a promoter is reported. This procedure allowed the preparation of various carbamates, thiocarbamates, and ureas in good yields directly from the corresponding hydroxamic acids. (C) 2009 Elsevier Ltd. All rights reserved.
