base-mediated hydroamination protocol, using substoichiometric amounts of a hydrosilane and potassium tert-butoxide, that operates under mild conditions at 30 °C. Many aryl- and heteroatom-substituted olefins as well as arylamines are tolerated, affording the desired products with complete regioselectivity. Preliminary mechanistic investigations reveal a non-radical pathway for hydroamination. A sequential
我们提出了一种碱介导的加氢胺化方案,使用亚化学计量的氢硅烷和叔丁醇钾,在 30°C 的温和条件下运行。可以耐受许多芳基和杂原子取代的烯烃以及芳基胺,从而提供具有完全区域选择性的所需产物。初步的机理研究揭示了加氢胺化的非自由基途径。还开发了一种顺序远程加氢胺化策略,包括初始 Fe 催化的烯烃异构化,然后是我们的碱介导的加氢胺化,以直接从末端脂肪族烯烃中获取 β-芳基胺。
