ELECTROPHILIC ALKENYLATION OF FLUOROOLEFINS BY PERFLUORO(2-ALKOXYPROPENES)

Perfluoro(2-alkoxypropenes) react with tetrafluoroethylene under mild conditions in the presence of SbF5 to give the corresponding perfluoro(2-alkoxy-2-pentenes). 1-Trifluoromethoxyperfluoropropene is converted by the action of SbF5 in SO2ClF solution to the acid fluoride derivative of perfluoroacrylic acid.

Novel synthetic route to perfluoroallyl cyanide (PFACN) reacting perfluoroallyl fluorosulfonate with cyanide

A novel synthetic method for the preparation of perfluoroallyl cyanide CF2[dbnd]CFCF2CN (PFACN) is presented. This includes the addition – elimination reaction of cyanide anion with perfluoroallyl fluorosulfate CF2[dbnd]CF

Synthesis and polymerization of a novel perfluorinated monomer

Perfluoro(5-methylene-2,2-dimethyl-1,3-dioxolane) (1) was synthesized by utilizing a direct fluorination reaction. Compound 1 was an entirely novel monomer with difluoromethylene at position 5 on the dioxolane ring as an unprecedented polymerization site. It successfully polymerized with tetrafluoroethylene to afford copolymers, which had Tg values in the range of 60-90 °C. The content of monomer 1 in the obtained polymers was less than 20 mol%, which seemed insufficient for giving various unique properties to polymers. However, each polymer was expected to be a superior material because of their advanced thermal stability. Comparison with copolymers of 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole and tetrafluoroethylene is also discussed.

EINSTUFIGE HERSTELLUNG HALOGENIERTER CARBONSAUREFLUORIDE AUS DEN FREIEN SAUREN

The reaction of per- or polyhalogenated carboxylic acids with trifluoromethyl or difluorochloromethyl substituted aromatics takes place in the presence of Lewis-acid-catalysts and forms the corresponding acid fluorides in good to very good yields.

Catalytic Conversion of Fluoroalkyl Alkyl Ethers to Carbonyl Compounds

Fluoroalkyl alkyl ethers are generally available by attack of alkoxide ion on fluoro olefins.In the presence of Lewis acid catalysts, such methyl and ethyl ethers have now been found to lose methyl or ethyl fluoride, respectively, to give fluorinated carbonyl compounds.The carbonyl compounds include acid fluoride, ketone, keto ester, vinyl ketone, acyl ketene, ketene, and acryloyl fluoride.
