REACTION OF 2-TRIFLUOROMETHYLPERFLUORO-2-PENTENYL FLUOROSULFATE WITH NUCLEOPHILIC REAGENTS

2-Trifluoromethylperfluoro-2-pentenyl fluorosulfate undergoes SN2' nucleophilic reactions.The reaction of this fluorosulfate with halide salts gives an equilibrium mixture of 1-halo-2-trifluoromethylperfluoro-2-pentene and 2-trifluoromethyl-3-haloperfluoro-1-pentene.

Functionalization of saturated fluorocarbons

A method is described for transforming perfluoroalkanes and perfluorocycloalkanes bearing tertiary fluorine into perfluoroenolates, which can be variously derivatized.

OLIGOMERIZATION OF PERFLUOROPROPYLENE CATALYZED BY ?-BIS(ARENE)CHROMIUM(0) COMPLEXES

Oligomerization of perfluoropropylene catalyzed by four ?-bis(arene)chromium(0) complexes (arene = benzene, diphenyl, 1,3,5-trimethylbenzene and hexamethylbenzene) were compared.Besides dimers (I, II) and trimers (III, IV) reported previously , two defluorotrimers VA and VB were found to be present in the oligomer mixtures.The formation of VA and VB was shown to be derived from trimer IV by hydrogenation followed by elimination of two moles of hydrogen fluoride.

Reactions Involving Fluoride Ion. Part 40. Amines as Initiators of Fluoride Ion Catalysed Reactions

Tetrakis(dimethylamino)ethene (TDAE) and trimethylamine react with anhydrous unsaturated fluorocarbons to produce, 'in situ', powerful fluoride-ion sources.These are used to iniate carbon-carbon bond forming reactions eg. oligomerisation and polyfluoroalkylation, and many of these reactions occur efficiently in the absence of a solvent.

Synthesis method of heptafluoroisobutyronitrile

The invention provides a synthesis method of heptafluoroisobutyronitrile. The synthesis method comprises the following steps of: A) carrying out ozone cracking on a hexafluoropropylene dimer in the presence of a fluorocarbon solvent and alcohol to prepare heptafluoroisobutyrate; and B) carrying out a reaction between the obtained heptafluoroisobutyrate with ammonia, and dehydrating to obtain heptafluoroisobutyronitrile. DHFP dimer ozone cracking reaction conditions are mild, the raw material conversion rate and the product yield are high, and the whole production process is safe, simple, convenient and reliable in technological operation and easy for industrial production.

Synthesis method and application of perfluoro(2-methyl-3-pentanone)

The invention relates to a synthesis method and application of perfluoro(2-methyl-3-pentanone), and belongs to the technical field of organic synthesis. The synthesis method comprises the following steps: mixing perfluoro(4-methylpent-2-ene) with a solvent; cooling to 13-17 DEG C; adding an oxidant; collecting a reaction product with the largest specific gravity to obtain a perfluoroepoxide; isomerizing the perfluoroepoxide in the presence of the solvent and an amine catalyst; collecting a reaction product with the largest specific gravity; and rectifying and collecting rectification products having a boiling point of 48 to 50 DEG C to obtain the perfluoro(2-methyl-3-pentanone), wherein the solvent comprises acetonitrile and/or dimethylformamide. The synthesis method has the advantages of simple process and relatively high product purity and synthesis yield; the synthesized perfluoro(2-methyl-3-pentanone) can be used as a fire extinguishing agent for fire extinguishing, and is good in fire extinguishing effect, green and environmentally friendly.
