Abstract (en)
[origin: WO2010014548A2] A process for the preparation of perfluorinated cis-alkene comprising: reducing a perfluorinated alkyne with hydrogen over a palladium catalyst in the presence of a non-aromatic amine catalyst modifier to form a product which comprises a perfluorinated cis-alkene, wherein the perfluorinated alkyne has the general structure: RfC=CRf wherein Rf is a perfluorinated alkyl group having a carbon number in the range between about 1 to 6.
