Potassium fluoride and cesium fluoride m formamide, N-methylformamide, or acetamide are efficient fluorinatingagents. They can be used for the enantiocontrolled synthesis of 2-fluorocarboxylic acids 1a and 1-fluoroalkyl benzenes 1b from the corresponding sulfonates which are easily available in high enantiomeric purity. The scope and limitation of the synthetic method is discussed.
