    摘要: AROMATIC CARBOXYLIC ACID FLUORIDES CAN BE MADE BY REACTING AROMATIC SULFONYL HALIDES WITH CARBON MONOXIDE AND AN ALKALI METAL FLUORIDE IN THE PRESENCE OF A CATALYST OF RU, RH OR PD. THE REAGENTS SHOULD BE FREE OF HYDROGEN AND SUBSTITUENTS OR SUBSTANCES WHICH CAN BE DEHYDROGENATED UNDER THE CONDITIONS OF THE REACTION TO YIELD HYDROGEN. THE AROMATIC ACID FLUORIDES ARE USEFUL AS ANALYTICAL REAGENTS AND FOR THE PRODUCTION OF POLYAMIDE OR POLYESTER POLYMERS.
