Abstract
A number of reagents used to prepare carboxamides via a carboxylic-phosphoric anhydride intermediate have been reexamined. It was found that a simple carboxylic-phosphoric anhydride prepared from a carboxylic acid and commercially available diethyl chlorophosphate provided several significant advantages over more complex intermediates in many cases.
