Abstract
The conversion of SO into arylsulfones under metal-free conditions was achieved for the first time by reacting SO 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 SO in promoting C-Si bond cleavage.
摘要
首次在无金属条件下通过 SO 与（杂）芳基硅烷和卤代烷烃在氟源存在下反应实现了芳基砜的转化。基于 DFT 计算阐明了这种转化的机制，该计算突出了 SO 在促进 C-Si 键断裂方面的影响。
