B(C6F5)3-hydrosilane pair enables the regioselective ring contraction of saturated cyclic hydroxylamines as well as the skeletal reorganization of acyclic derivatives. The method overcomes the limitations of traditional uncatalyzed Stieglitz rearrangements, allowing for swift structural transformations between different types of amines. The mechanism of this rearrangement is investigated by control experiments
B(C 6 F 5 ) 3 -氢硅烷对促进的新型重排能够实现饱和环状羟胺的区域选择性环收缩以及无环衍生物的骨架重组。该方法克服了传统非催化施蒂格利茨重排的局限性,允许不同类型胺之间的快速结构转变。通过控制实验和 DFT 计算研究了这种重排的机制。
