Perfluoro-3- propanoic

In a novel procedure, chemical modification of uncrosslinked atactic polystyrene by acetylation followed by a Claisen condensation with ethyl perfluoro-propanoate has been used to prepare a macromolecular ligand bearing phenyl,... 

Electrochemical fluorination of a-cyclohexenyl-substituted carboxylic (acetic, propanoic, butanoic, and pentanoic) acid esters (methyl, ethyl, and propyl) results in a series of both perfluoro-9-alkyl-7-oxabicyclo[4 3 OJnonanes and per-fluoro-8-alkoxy-9-alkyl-7-oxabicyclo[4.3.0]nonanes [<8S] (equation 19)... 

The relative ease of acid hydrolysis of perhalomethyl groups attached to a polyfluoroalkane chain has been suggested to take the following order CBrCIF > CCl3 > CBrF2.27 For example, l-bromo-3,3.3-triehloro-l,l,2,2-tetrafluoropropane is hydrolyzed to give perfluoro-3-bromo-propanoic acid (22).27...
