, p. 137 - 141 (2003)
A manipulatively one-pot and rapid method for the synthesis of carboxylic sulfonic anhydride from acid chloride or sulfonyl chloride and potassium salt of carboxylic or sulfonic acid under solvent-free conditions is reported. The reaction has been carried out in excellent yield and short reaction time in the presence of DABCO under solvent-free conditions.

, p. 745 - 747 (2007/10/02)
A convenient one-pot procedure is reported for the preparation of carboxamides and carboxylic acid esters from carboxylic acids and amines or alcohols, respectively.The carboxylic acids are activated by sulfonyl chlorides under solid-liquid phase-transfer conditions using solid potassium carbonate as base and a lipophilic quaternary ammonium salt as catalyst.
