C–N2 bond cleavage. This unified strategy has been achieved by the synergistic combination of visible-light metal-free photoredox and palladium catalysis under silver-, base- and/or additive-free conditions. The broad substrate scope, functional group tolerance, excellent regioselectivity and redox-neutral conditions of this process make it attractive for the effective synthesis of a wide range of important
在这里,我们报告的C-H键与芳基重氮盐作为一个简单的芳基供体室温下直接芳基化的双催化方法中,也正在作为内部氧化剂通过C-N 2键断裂。通过在无
银,无碱和/或无添加剂的条件下,将无可见光
金属的光氧化还原和
钯催化的协同结合,可以实现这种统一的策略。该方法广泛的底物范围,官能团耐受性,出色的区域选择性和氧化还原中性条件使其对有效合成各种重要的N杂环商品(例如二苯并[ b,d ]氮杂,
咔唑和
菲啶)具有吸引力。
