title: Synthesis of Aromatic Sulfones from SO2and Organosilanes Under Metal-free Conditions.
abstract: The conversion of SO2into arylsulfones under metal-free conditions was achieved for the first time by reacting SO2with (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 SO2in promoting C-Si bond cleavage.
