Diarylsulfur(<scp>VI</scp>) Oxide Difluoride by Direct Fluorination of Sulfoxides

Abstract

Use of fluorine as fluorinating agent permits the first transformation of sulfoxides (1) into the title compounds (2) under mild conditions in the liquid phase. The formation of an oxo cation from (2) with a new fluoroorgano periphery (R  aryl) is remarkable.
