摘要：

Carbamoyl imidazolium salts are demonstrated to act as useful carbamoylation reagents, in reactions with alcohols, phenols, thiols and thiophenols to form carbamates and thiocarbamates under relatively mild conditions. The salts are stable and easily prepared from the corresponding amines using CDI. (C) 1999 Elsevier Science Ltd. All rights reserved.
