Usage

General Description

2-Fluoropropane, also known as isopropyl fluoride, is a colorless, flammable organic compound with the chemical formula C3H7F. It is a halogenated hydrocarbon and is derived from propane by replacing one of the hydrogen atoms with a fluorine atom. 2-Fluoropropane is used as a refrigerant and as a propellant in aerosol products. It is also used as a solvent and in the production of other chemicals. However, it is considered to be a hazardous compound and should be handled with caution due to its flammability and potential health effects if inhaled or ingested.

Fluorination of Alkanes by Chlorine Trifluoride. Hydride Abstraction Mechanism

Addition of chlorine trifluoride to a solution of alkane in Freon or liquid carbon dioxide at -75 deg C gives good yields of monofluoroalkane along with difluoro- and trifluoroalkanes in amounts dependent on reactant proportions.The inorganic products are HF and ClF.The reaction is highly selective for 3 over 2 positions.Methane and hexamethylethane are unreactive.Neohexane fluorinates with rearrangement, but 2-fluoro-3,3-dimethylbutane exposed to the postreaction medium does not rearrange.A hydride abstraction mechanism is inferred.

Fluorination of propane and propene over cobalt(III) trifluoride and potassium tetrafluorocobaltate(III)

Fluorination of propane and propene over cobalt(III) fluoride and potassium tetrafluorocobaltate(III) gave complex mixtures of products which have been identified to the 0.5percent level.The reactions are valuelles for preparative purposes.The mechanism of the fluorinations is not a simple F-for-H replacement, but requires an initial conversion of propane into propene followed by carbocation- and radical mediated reactions: the carbocations can be quenched by fluoride ions, rearrange and eliminate, and the radicals can be oxidised to carbocations or quenched by fluorine atoms.Radical quenching tends to predominate late in the fluoronation and carbocation reactions at the beginning.

Evidence for Carbocation Intermediates in the TiO2-Catalyzed Photochemical Fluorination of Carboxylic Acids

Laser flash photolysis/transient absorbance spectroscopy was used to determine the mechanism of photo-Kolbe fluorination of carboxylic acids, RCOOH --> RF, at colloidal TiO2 suspensions in acetonitrile.Transient absorption spectra of Ph3C(+), Ph3C(*), Ph2CH(*) and Ph2CH(+) were observed from the photooxidation of Ph3CCOOH and Ph2CHCOOH at TiO2 using 355-nm excitation.Transient decays, monitored in the presence and absence of fluoride ions, showed that the carbocations reacted rapidly with fluoride, but the neutral radicals did not.By varying the laser intensity, it wa s found that the photooxidation of Ph3CCOOH to Ph3C(*) at TiO2 occured via a single-photon process, while the formation of of Ph3C(+) required two photons.This finding is in agreement with the parabolic light intensity dependence of initial reaction rates in bulk photolysis experiments.Although fluoride is strongly adsorbed on the TiO2 surface in acetonitrile solution, the oxidizing power of photogenerated holes could be increased by coordinating HF to F(-), and therefore the threshold for oxidative photochemical fluorination was extented to more positive potentials.In this way less easily oxidized carboxylic acids RCOOH could be converted to RF.
