WebFormation of Acid Halides. Carboxylic acids react with thionyl chloride ( S O C l 2) to form acid chlorides. During the reaction the hydroxyl group of the carboxylic acid is converted to a chlorosulfite intermediate making it a better leaving group. The chloride anion produced during the reaction acts a nucleophile. WebCarboxylic acids react with phosphorous trichloride (PCl 3 ), phosphorous pentachloride (PCl 5 ), thionyl chloride (SOC l 2 ), and phosphorous tribromide (PBr 3) to form acyl halides. Acid anhydride formation. Following is the anhydride group: This group forms by reacting the salt of a carboxylic acid with an acyl halide. Decarboxylation reaction.
