Process for the preparation of 2-fluorobenzonitrile from saccharin

The present invention relates to a process for the preparation of 2-fluorobenzonitrile. The process comprises the steps of: (a) heating saccharin and phosphorus pentachloride under conditions and for a time sufficient to provide 2-cyanobenzenesulfonyl chloride; and (b) reacting the 2-cyanobenzenesulfonyl chloride with alkali metal fluoride in solvent for said 2-cyanobenzenesulfonyl chloride under conditions and for a time sufficient to provide 2-fluorobenzonitrile. The present invention provides a process for the preparation of 2-fluorobenzonitrile which is a versatile intermediate for a variety of 2-fluoro substituted benzenes. For example, hydrolysis of 2-fluorobenzonitrile leads to 2-fluorobenzoic acid or 2-fluorobenzamide while reduction of 2-fluorobenzonitrile leads to 2-fluorobenzylamine. Also, the reaction of 2-fluorobenzonitrile with organometallic reagents results in various 2-fluorophenyl ketones.
