The first metal-free procedure for the synthesis of arylsulfonyl fluorides is reported. Under organo-photoredox conditions, aryl diazonium salts react with a readily available SO2 source (DABSO) to afford the desired product through simple nucleophilic fluorination. The reaction tolerates the presence of both electron-rich and -poor aryls and demonstrated a broad functional group tolerance. To shed
报道了合成芳基磺酰氟的第一个无金属程序。在有机光氧化还原条件下,芳基重氮盐与容易获得的 SO 2源 (DABSO)反应,通过简单的亲核氟化得到所需的产物。该反应耐受富电子和贫电子芳基的存在,并表现出广泛的官能团耐受性。为了阐明反应机理,结合了几种实验技术,包括荧光、核磁共振和 EPR 光谱以及 DFT 计算。
