摘要

Abstract A novel and facile synthesis of carboxylic anhydrides from carboxylic acid using 4, 5- dichloro-2-[(4-nitrophenyl) sulfonyl] pyridazin-3 (2H)-one (2) is presented. Treatment of aliphatic or aromatic carboxylic acids with 2 in the presence of base in organic solvents gave the corresponding anhydrides in good or excellent yields
