Perfluoro(methyldecalin is suitable reagent used to investigate the reactions of iodide anions and anions derived from glow discharge ionization of perfluoro(methyldecalin) with positive ions derived from poly(ethylene glycol).It is suitable reagent used for the oxidation of alcohols with the ruthenium porphyrin at higher temperatures (140oC) and elevated oxygen pressures (50psi).Perfluoro(methyldecalin (Perfluoro-1-Methyldecalin) may be used in the preparation of undecafluoro-6-trifluoromethyltetralin via defluorination.
