Ligand-controlled reactivity plays an important role in transition-metal catalysis, enabling a vast number of efficient transformations to be discovered and developed. However, a single ligand is generally used to promote all steps of the catalytic cycle (e.g., oxidative addition, reductive elimination), a requirement that makes ligand design challenging and limits its generality, especially in relay
配体控制的反应性在过渡金属催化中起着重要作用,可以发现和开发大量有效的转化。然而,单个配体通常用于促进催化循环的所有步骤(例如,氧化加成、还原消除),这一要求使得配体设计具有挑战性并限制了其通用性,尤其是在中继不对称转化中。我们假设具有金属中心的多个配体可用于顺序促进多个催化步骤,从而通过简单配体的简单组合来结合互补的催化反应性。通过这种中继催化策略(L/L*),我们在此报告了第一个高度区域选择性和对映选择性远程加氢芳基化过程。3 )-H芳基化过程。
