We present the coupling of primary and secondary benzyl alcohols with indoles to form 3-benzylated indoles and H2O that is catalyzed, for the first time, by a complex of earth-abundant iron. This transformation accommodates a variety of substrates and is distinguished by its operational simplicity, sustainability, high functional-group tolerance, and amenability to gram-scale synthesis. On the basis
我们提出伯和仲苄醇与吲哚的偶合,以形成3-苄基化的吲哚和H 2 O,这是第一次由富地球的铁的复合物催化。这种转变可容纳多种底物,并且以其操作简单,可持续性,高官能团耐受性和对克级合成的适应性而著称。根据初步的实验观察,我们建议反应通过借入氢过程进行。
