A good yield, high reaction rate process is disclosed for the production of perfluoro(alkyl vinyl ethers). The process involves elimination of halogen, preferably chlorine, from carbon atoms .alpha. and .beta. to an ether oxygen in an .alpha.,.beta.-dihaloperfluoro ether wherein the .alpha.,.beta.-dihaloperfluoro ether is allowed to react with zero valent zinc in a pyrrolidinone solvent. More particularly, the inventive process relates to high yield production of CF.sub.2.dbd.CFOCF.sub.2 CF.sub.2 SO.sub.2 F from CF.sub.2 ClCFClOCF.sub.2 CF.sub.2 SO.sub.2 F wherein CF.sub.2 ClCFClOCF.sub.2 CF.sub.2 SO.sub.2 F is allowed to react with zero valent zinc in the presence of N-methyl-2-pyrrolidinone.

Um rendimento bom, processo elevado da taxa da reação é divulgado para a produção de ethers do vinil do perfluoro(alkyl). O processo envolve o elimination do halogênio, preferivelmente cloro, do alpha. dos átomos de carbono e do beta. a um oxigênio do ether em um alpha., ether de.beta.-dihaloperfluoro wherein o alpha., ether de.beta.-dihaloperfluoro é permitido reagir com o zinco valent zero em um solvente do pyrrolidinone. Mais particularmente, o processo inventive relaciona-se à produção elevada do rendimento de CF.sub.2.dbd.CFOCF.sub.2 CF.sub.2 SO.sub.2 F de CF.sub.2 ClCFClOCF.sub.2 CF.sub.2 SO.sub.2 F wherein CF.sub.2 ClCFClOCF.sub.2 CF.sub.2 SO.sub.2 F é permitido reagir com o zinco valent zero na presença de N-methyl-2-pyrrolidinone.
