Methods of halogenating a carbon containing compound having an sp3 C-H bond are provided. Methods of fluorinating a carbon containing compound comprising halogenation with Cl or Br followed by nucleophilic substitution with F are provided. Methods of direct oxidative C-H fluorination of a carbon containing compound having an sp3 C-H bond are provided. The halogenated products of the methods are provided.
We disclose a new approach to the catalysis of alkane fluorination employing ultraviolet light and a photosensitizer, 1,2,4,5-tetracyanobenzene (TCB).

Several hydrocarbons reacted with caesiumfluoroxysulphate 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

Nitrosoniumtetrafluoroborate in conjunction with pyridiniumpoly(hydrogenfluoride) has been found to be excellent desulfurativefluorination reagent. In NO+BF4−/PPHF system, mono-fluorides and gem-difluordes have been obtained in high yields from the corresponding phenylsulfides and dithiolane derivatives, respectively.
