A mild and efficient electrochemical method for radical addition, cyclization, and migration reaction was described in this work. A difluoromethyl radical was produced by anodizing CF2HSO2Na. The resulting product was then added to olefin, underwent Smiles cyclization, and migrated to form β-difluoromethamide compounds after the release of SO2. The process was free from metals and catalysts, gram-grade
这项工作描述了一种温和有效的自由基加成、环化和迁移反应的电化学方法。通过阳极氧化CF 2 HSO 2 Na产生二氟甲基自由基。然后将所得产物添加到烯烃中,进行Smiles环化,并在释放SO 2后迁移形成β-二氟甲酰胺化合物。该工艺不含金属和催化剂,是克级的,并且对各种富电子基材具有耐受性。
