ABSTRACT:
A method is disclosed for producing fluoronitrobenzene compounds by reacting chloronitrobenzene compounds with a fluoride salt in the presence of a tetramethylammonium salt phase-transfer catalyst. This catalyst allows the use of elevated reaction temperatures with substantial freedom from catalyst inactivation, resulting in yields and reaction rates which are improved over those of previously known methods using higher molecular weight quaternary ammonium salt phase transfer catalysts having more total carbon atoms in their ammonium cations.
