ABSTRACT:
A method for producing fluoronitrobenzene compounds by reacting chloronitrobenzene compounds with a fluoride salt in the presence of a quaternary ammonium salt phase-transfer catalyst, wherein the catalyst is added to the reaction mixture incrementally during the course of the reaction. The incremental addition of catalyst allows the use of elevated reaction temperatures which, although sometimes causing catalyst inactivation, result in yields and reaction rates which are improved over those of methods involving a single catalyst addition.
