In analogy to the classical reaction of C−B bonds with peroxides, the first oxidative functionalization of aminoboranes through a 1,2‐N migration was realized. Readily available aliphatic nitro compounds are thereby transformed into N‐ and O‐functionalized hydroxylamines in a single synthetic operation. Addition of hazardous peroxides is avoided. Instead, the insertion of O2, as the terminal oxidant
类似于C-B键与过氧化物的经典反应,通过1,2-N迁移实现了氨基硼烷的第一个氧化功能化。易于获得的脂肪族硝基化合物可通过一次合成操作转化为N和O功能化的羟胺。避免添加有害的过氧化物。相反,将O 2作为末端氧化剂插入Zn-C键可提供必要的过氧化物。反过来,所需的锌有机基团是通过硼与锌的交换,由硝基向氨基硼烷转化的有机硼酸酯副产物形成的。
