ABSTRACT:
In a process for preparing a 2-(fluoronitrobenzene)acetonitrile by reacting a fluoronitrobenzene with an alpha,alpha-disubstituted acetonitrile in an inert solvent and in the presence of a base, the temperature is maintained not higher than about 15.degree. C. to lead to the formation of a 2-(fluoro-2-nitrobenzene)acetonitrile. Preferred reactants are 2-fluoronitrobenzene and 2-chloropropionitrile, which lead to the formation of 2-(3-fluoro-2-nitrobenzene)propionitrile.
