general zinc‐mediated intermolecular reductive radical fluoroalkylsulfination of unsaturated C−C bonds has been developed using readily available fluoroalkyl bromides and 1,4‐diazabicyclo[2.2.2]octane‐bis(sulfur dioxide) adduct (DABSO) with wide substrate scope and excellent functional group tolerance. Sulfur dioxide anion radical generated in situ from the reduction of sulfur dioxide with zinc may be
使用易于获得的氟代烷基溴和具有宽底物的1,4-二氮杂双环[2.2.2]辛烷-双(二氧化硫)加合物,开发了一种通用且通用的锌介导的不饱和C-C间分子间还原性自由基氟代烷基硫化物。范围和出色的功能组耐受性。由锌还原二氧化硫而原位产生的二氧化硫阴离子自由基可能参与了反应机理。
