molecules considering the readily available aldehyde and ketone compounds. The present approaches typically rely on strategies via carbene, carbanion, or carbocation equivalents. Herein, combined with dual nickel/photoredox catalysis regime, we developed a strategy through a radical intermediate to achieve the deoxygenative arylboration of aldehydes. Compared with the known patterns of carbon–oxygen (C–O)
考虑到容易获得的醛和酮化合物,羰基的脱氧双官能化代表了构建复杂分子的便捷途径。目前的方法通常依赖于通过卡宾、碳负离子或碳阳离子等价物的策略。在此,结合双
镍/光氧化还原催化方案,我们开发了一种通过自由基中间体实现醛脱氧芳基
硼化的策略。与已知的碳-氧 (C-O) 键转换模式相比,这种 C-OBPin 单元的耦合为这种
化学开辟了方向。在非常温和的条件(可见光、环境温度、无强碱)下,带有不同官能团的多种底物与该方法相容,以提供苄基
