Synthesis of Aromatic Sulfones from SO₂ and Organosilanes Under Metal‐free Conditions

Abstract

The conversion of SO₂ into arylsulfones under metal-free conditions was achieved for the first time by reacting SO₂ with (hetero)arylsilanes and alkylhalides in the presence of a fluoride source. The mechanism of this transformation was elucidated based on DFT calculations, which highlight the influence of SO₂ in promoting C-Si bond cleavage.
