General Description

HEPTAFLUORO-2-NITROSOPROPANE is a fluorinated organic compound with the chemical formula C3F7NO. It is a colorless, odorless gas at room temperature and pressure. HEPTAFLUORO-2-NITROSOPROPANE is used as a solvent in chemical synthesis and as a propellant in aerosol products. It is also a potential greenhouse gas with a high global warming potential. Due to its potential environmental and health hazards, efforts are being made to limit its use and find more sustainable alternatives.

Conversion of Fluorocarbon Olefins into Perfluoro-ketoximes

Treatment of perfluoro-2-nitrosopropane and perfluoronitrosocyclobutane with aqueous potassium bisulphite yields the oximes of perfluoroacetone and perfluorocyclobutanone, respectively; the nitroso-compounds are easily prepared via indirect addition of nitrosyl fluoride across the double bonds in perfluoropropene and perfluorocyclobutene.

Fluorocarbon Derivatives of Nitrogen. Part 6. Reactions of Some Perfluorinated Nitroso-compounds with Hydrogen Sulphite Ion: Conversion of Fluorocarbon Olefins into Perfluoro-ketone Oximes

The sequence of events R1FR2FCFNO + HSO3-aq. -> R1FR2FCFN(OH)SO3- -> R1FR2FCFNHOH -> R1FR2FC=NOH is proposed to account for the production of N-trifluoromethylhydroxylamine, perfluoropropanohydroximoyl fluoride, perfluoroacetone oxime, and perfluorocyclobutanone oxime when the nitroso-compounds CF3NO, n-C3F7NO, (CF3)2CFNO, and (*)CF2CF2CF2C(*)FNO, respectively, are treated with aqueous potassium hydrogen sulphite; understandably, perfluoro-1-nitrosopropane reacts with the same reagent in the presence of lead(IV) oxide to give the purple water-soluble oxyl n-C3F7N(O.)SO3-K+.Since perfluoro-2-nitrosopropane and perfluoronitrosocyclobutane are easily obtained via the route R1FCF=CFRF -> (with KF-CF3CO2Ag)R1FCFAgCF2RF -> (with NOCl) R1FCF(NO)CF2RF (R1F = CF3, RF = F; R1FRF = CF2CF2)(RFCF2 = R2F), the reductive defluorination with aqueous hydrogen sulphite anion completes a fluorocarbon olefin -> fluorocarbon ketone oxime conversion.
