Methyl perfluoro

Fluorination of phenylacetic acid over potassium tetrafluorocobaltate(lll) at 360 "C gives65 a very low yield of methyl perfluoro(cyclohexylacetate) (workup by methanol treatment). [Pg.667]

Perfluoroalkylcopper reagents are the most studied perfluoroalkyl organometallic reagents due to their unique combination of thermal stability and chemical reactivity. They are readily prepared by copper metal insertion reactions with perfluoroalkyl halides in a coordinating solvent (e.g., formation of decarboxylation reactions of perfluoroalkanoic acid salts and copper(I) halide (e.g., formation of 2 ), or metathesis reactions (e.g., formation of 4 via 3 ). (Trifluoro-methyl)copper (4) has also been recently accessed by decomposition of methyl 2,2-difluoro-2-(fluorosulfonyl)acetate (5) or methyl perfluoro [2-(fluorosulfonyl)ethoxy]acetate (6) in the presence of copper(I) iodide and by reaction of trimethyl(trifluoromethyl)silane (7) with fluoride and copper(I) iodide. ...

The synthesis of carboxylated perfluorovinyl ether was very difficult and no preparative method had been known before. Recently, however, several synthetic methods have been proposed. An example of the synthetic route to methyl perfluoro-5-oxa-6-heptenoate (M ) and methyl perfluoro-5,8-dioxa-6-methyl-9-decenoate (M2) is shown in the following scheme. [Pg.423]

In the polymerization of vinyl esters of perfluorinated acids, ordinary organic solvents are not suitable because of the low solubility, particularly of the higher esters. Therefore, fluorinated solvents have been suggested. Methyl perfluoro-butyrate is considered satisfactory. While benzotrifluoride may be used, the polymers produced in this solvent are low molecular weight [91]. [Pg.236]
