摘要/Abstract
A facile and efficient method for the synthesis of sulfonated or sulfenylated pyrazolones catalyzed by KIO3 was established. A variety of desired products were obtained in moderate to high yields. This methodology could be conducted under mild reaction conditions without requiring any metal. Control experiments showed that the mechanism of this reaction was different from previous KIO3-catalyzed reactions. Some of these desired products showed high inhibitory activity against V. mali and B. cinerea.
