Formation of carboxamides of a variety of carboxylic acids with the coupling reagent BBDI is described, This procedure permits a one pot and simple operation without the need of any bases and no base was required for even use of amine hydrochlorides. In addition, an approach to BBDI-catalyzed carboxamidation is examined. (C) 2008 Elsevier Ltd. All rights reserved.
