The advent and development of photoredox/nickel synergistic catalysis have enabled the use of various alkyl radical precursors in the cross-coupling arylation, yet none has addressed the challenge of regiodivergent synthesis. Herein, we disclose a visible light nickel-catalyzed protocol for the deaminative cross-coupling of redox-active imines with various electrophiles that allow for the rapid construction
光氧化还原/镍协同催化的出现和发展使得能够在交叉偶联芳基化中使用各种烷基自由基前体,但尚未解决区域发散合成的挑战。在此,我们公开了一种可见光镍催化方案,用于氧化还原活性亚胺与各种亲电试剂的脱氨基交叉偶联,从而以区域分散的方式快速构建富含 C(sp 3 ) 的芳烃结构。该协议成功的关键是现成的有机光催化剂和路易斯酸添加剂的结合。作为烷基芳烃的另一种方法,我们还展示了亲电试剂的性质决定了区域化学结果。
