C–C bond through a radical process is described. The sequence comprises an initial in situ generation of a putative iron hydride followed by a hydrogen atom transfer to an alkene, a coupling with a hydrazone, and a final reduction of the nitrogen-centered radical. Hydrogenation of the obtained hydrazines renders amines, including valuable tert-alkyl amines.
描述了一种通过自由基过程将烯烃与醛或酮衍生的Cbz-hydr偶联以形成新的C-C键的方法。该序列包括初始原位生成假定的氢化铁,然后将氢原子转移至烯烃,与hydr偶联以及以氮为中心的自由基的最终还原。所获得的肼的氢化产生胺,包括有价值的叔烷基胺。
