strength of their carbon–nitrogen bond. Here, we disclose that several ammonium salts can be readily activated using iridium photoredox catalysis to form radicals and illustrate the synthetic utility of this activation of strong C–N bonds with hydrodeamination reactions and radical couplings. Cyclic voltammetry was exploited to rationalize the reactivity observed for the activation of these ammonium
由于铵盐的碳-氮键强度,通常认为铵盐很难还原成相应的自由基。在这里,我们公开了几种铵盐可以很容易地使用铱光氧化还原催化活化以形成自由基,并说明了这种通过加氢脱氨反应和自由基偶联激活强 C-N 键的合成效用。利用循环伏安法来合理化观察到的这些铵盐活化的反应性。
