- PROCESS FOR THE PREPARATION OF ORGANIC HALIDES
-
The present invention provides a halo-de-carboxylation process for the preparation of organic chlorides, organic bromides and mixtures thereof, from their corresponding carboxylic acids, using a chlorinating agent selected from trichloroisocyanuric acid (TCCA), dichloroisocyanuric acid (DCCA), or combination thereof, and a brominating agent.

- REACTIONS OF ORGANIC COMPOUNDS WITH SF4-HF-HALOGENATING AGENT SYSTEMS VI. REACTIONS OF BENZENE AND ITS DERIVATIVES WITH SF4-HF-Cl2(Br2)
-
In the reactions of benzene-carboxylic and -dicarboxylic acids with SF4-HF-Cl2(Br2), apart from the conversion of carboxyls into trifluoromethyl groups, there occurs the halogenation of the benzene ring with the formation of the corresponding chloro- and bromo-containing (trifluoromethyl)- and bis(trifluoromethyl)-benzenes.
