| titleOfInvention | Production of n-fluoro-2,3,4,5,6-pentachloro-pyridinium salt |
| abstract | PURPOSE: To produce the title compound in high yield safely by reaction between pentachloropyridine, fluorine and a Brϕnsted acid or Lewis acid in an acidic lower perfluoro saturated fatty acid as a solvent. n CONSTITUTION: In a lower perfluoro saturated fatty acid such as trifluoro-aceteic acid or pentafluoropropionic acid, the reaction of penta-chloropyridine with fluorine and a Brϕnsted acid of the formula: XH (X is Breϕnsted acid radical) such as trifluoromethanesulfonic acid is effected to give N-fluoro-2,3,4,5,6- pentachloro-pyridinium salt of formula I. Instead of the Brϕnsted acid, a Lewis acid is used to effect the reaction to give N-fluoro-2,3-4,5,6-pentachloropyridinium salt of formula II. The product is useful as a reagent for introducing simultaneously a fluorine atom and an acyloxy group into the double bond in an alkene. n COPYRIGHT: (C)1990,JPO&Japio |
