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.
