Abstract
HCl-H2O2 was used in the electrophilic chlorination of aromatic amines to replace liquid chlorine.Good results were obtained in the synthesis of 2,6-dichloro-4-trifluoromethylaniline and 4-chloro-2-trifluoromethylaniline.Bis(trichloromethyl)carbonate was applied in the synthesis of chrysanthemyl chloride,benzoyl chloride,benzesulfonyl chloride and imide chloride to replace such chlorination agents as thionyl chloride,sulfonyl chloride,phosphorusoxychloride,phosphorus pentchloride,phosphorus trichloride and phosgene.The two chlorination methods both give lower E factors.
