chemical science, this functional group represents a highly attractive starting material for forging new C–C bonds. Here, we demonstrate that the combination of anodic preparation of the alkoxy triphenylphosphonium ion and nickel-catalyzed cathodic reductive cross-coupling provides an efficient method to construct C(sp2)–C(sp3) bonds, in which free alcohols and aryl bromides—both readily available chemicals—can
由于醇在整个化学科学中无处不在,因此该官能团代表了一种极具吸引力的起始材料,可用于形成新的 C-C 键。在这里,我们证明了烷氧基三苯基鏻离子的阳极制备和镍催化的阴极还原交叉偶联的组合提供了一种构建 C(sp 2 )–C(sp 3 ) 键的有效方法,其中游离醇和芳基溴化物- 两种容易获得的化学品 - 可以直接用作偶联伙伴。这种镍催化的配对电解反应具有广泛的底物范围,具有广泛的功能,几种结构复杂的天然产物和药物的后期芳基化就说明了这一点。
