Abstract
Fluoro-derivs. of organic cpds. are prepd. by heating 200 degrees C a mixt. of aq. soln. of KF, organic halide, (except fluoride) and catalytic amt. of R1R2R3R4M +X- (where M is a gp BV pentavalent element, R1-4 are monovalent, <=10C hydrocarbon radicals, X- is chloride or bromide).The products are used as refrigerants, propellants and intermediates for plastics and organic synthesis. The process is simple and can be carried out at lower reaction temps.
