Potassium fluoride (69.6 g; 1.2 mole) and benzyltriethylammonium chloride (10.7 g; 0.05 mole) were added to molten 2-chloronitrobenzene (157.5 g; 1.0 mole). After stirring at 140° C. for 28 hours and a similar work-up to Example 1, 2-fluoronitrobenzene was obtained in 41% yield together with 7% recovered 2-chloronitrobenzene.
