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。

and 3-chlorostyrene in the presence of potassium tert-butoxide to give N-substituted 2,3-dihydroindoles in good yields. The combination of this domino-amination protocol with a suitable dehydrogenation reaction gives access to pharmacologically interesting indoles in a one-pot procedure. Overall product yields of N-substituted indoles >50% are obtained by this method starting from commercially available

dual-catalytic strategy for the radical decarboxylation functionalization of aliphatic carboxylic acids. The photoinduced ligand-to-iron charge transfer process under light was initially occurred to generate an unstabilized alkyl radical, and the copper catalyst delivered the radical and enabled the subsequent coupling reactions to form C–N or C–C bonds. By merging iron-catalyzed decarboxylation with copper catalysis
