PROCESS FOR PREPARING FLUOROBENZOLE

摘要

Fluorobenzenes are manufactured by reacting substituted chlorobenzenes with potassium fluoride in the presence of catalytic amounts of cesium fluoride and in the presence of certain solvents; m-nitrofluorobenzenes and m-cyanofluorobenzenes can also be manufactured in the absence of cesium fluoride. The products are starting materials for the manufacture of dyes, pharmaceuticals and pesticides.
