摘要：

3-Aroylethylsydnones react with excess hydrochloric acid at roam temperature to give 3-arylpyrazolines. At refluxing temperature and in the presence of ethyl acetate, 1-aroylethyl-3-arylpyrazolines are obtained. Similarly, decomposition of 3-aroylethyl-4-bromosydnones gives corresponding 1-chloroformylpyrazolines.
