摘要

ZnCl_2 is an efficient catalyst for synthesis of carboxylic acid anhydride from 2-acyI-4,5-dichloropyridazin-3(2H)-ones.Treatment of 2-acyl-4,5-dichloropyridazin-3(2H) -ones with ZnCl_2 (0.5 equivalents) and air in refluxing dry THF or acetonitrile gave the corresponding symmetric acid anhydrides in good to excellent yield.
