A one-step conversion of carboxylic acid to hydroxamic acid, under neutral pH conditions is described. This simple, selective and efficient method was applied to a wide range of aliphatic/aromatic carboxylic acid derivatives that contain hydroxyl, halo, ester and other base sensitive groups as substituents. The method utilizes cheaply available reagents and hence it is a practical and cost effective
