Several hydrocarbons reacted with caesium fluoroxysulphate in acetonitrile at 35° C yielding mono and disubstituted products. Fluorocyclohexane, fluorocycloheptane, and 2-exo- fluoronorbornane formed in the reactions with the corresponding hydrocarbons were accompanied by up to 15% of other unidentified fluoro products, but their amount was strongly diminished when fluorination was performed in the presence of nitrobenzene. ...
