Room-temperature fluorination of benzene with cesium fluoroxysulphate in the presence of boron trifluoride as catalyst resulted in the formation of fluorobenzene, while reaction with naphthalene gave 1-fluoro and 2-fluoronaphthalene in the ratio 5:1, the overall yield being between 38 and 42percent.The fluorination of phenanthrene and pyrene should be carried out at higher dilution and needs no catalyst.Phenanthrene gave 9-fluorophenanthrene and 9,9-difluoro-10-keto-9,10-dihydrophenanthrene in the ratio 1:6 in a yield of about 70percent, while pyrene gave 1-fluoro and 4-fluoropyrene in the ratio 7.5:1.
