Both stoichiometric and catalytic reactions have been developed and are of interest from the perspectives of organic synthesis and remediation of xenochemicals. Hydrofluorocarbons HFCs , such as tetrafluoroethane , serve as CFC replacements because they do not catalyze ozone depletion. Because natural sources of fluoro-organic compounds are extremely rare, the industrial synthesis of fluorinated organic compounds and production of fluorinated natural product derivatives have greatly expanded in recent years because of their increasing importance in the agrochemical and pharmaceutical industries. The C-F bond is found in pharmaceuticals , agrichemicals , fluoropolymers , refrigerants , surfactants , anesthetics , oil-repellents , catalysis , and water-repellents , among others.
