Continuous flow reaction system for the synthesis of 2,2,2-trichloroacetophenone derivatives and its application

초록

A continuous flow reaction system was developed for the synthesis of 2,2,2-trichloroacetophenone derivatives. When aryl propiolic acids and water were mixed with trichloroisocyanuric acid in DMF at 5 degrees C, the 2,2,2-trichloroacetophenone derivatives were formed within 5 min with good yields. In addition, the resulting mixture was flowed to react with amines to give the corresponding benzamide. This flow reaction system provided higher yields within shorter times than the batch reaction system. (C) 2018 Elsevier Ltd. All rights reserved.
