Abstract

Methylfluoride and hydrogen fluoride react with powerful methylating agent [SO₂Me]⁺ in a temperature-dependent addition reaction to form methylated fluorosulfuric acid [FS(OMe)₂][Sb₂F₁₁] and methylated fluorosulfuric acid methyl ester [FS(OH)(OMe)][SbF₆], respectively. The obtained methylated fluorosulfinic acid and methylated fluorosulfinic acid methyl ester were characterized by single X-ray structure analysis and vibrational spectroscopy.
