It is extremely rare for reactive intermediates to possess a ground state triplet character. Excited state triplet intermediates are generally accessed by means of photon transfer from a tunable light source or by using any triplet sensitizers. N‐acyl N‐alkoxy nitreniums are an important class of reactive intermediates in the synthetic organic community due to their prolonged lifetime and ground‐state singlet character. Herein, we report an external oxidant and toxic catalyst‐free mild electrochemical protocol to access nitrenium reactive intermediate. Experimental findings of the mechanistic pathway suggested a theoretically predicted triplet reactive intermediate that is energetically favorable to the singlet pathway.

电介导基态三重态氮物种诱导的双自由基极性反应

具有基态三重态特征的反应中间体极为罕见。激发态三重态中间体通常通过可调谐光源的光子转移或使用任何三重态敏化剂来获得。 N-酰基-N-烷氧基氮鎓由于其较长的寿命和基态单线态特征，是有机合成领域中一类重要的反应中间体。在此，我们报告了一种无外部氧化剂和有毒催化剂的温和电化学方案来获取氮反应中间体。机制途径的实验结果表明，理论上预测的三重态反应中间体在能量上有利于单重态途径。
