ABSTRACT:
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.
