A Facile Procedure for Preparation of Carboxylic Sulfonic Anhydrides Under Solvent-Free Conditions
摘要:
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.
