Neutral organic super electron donors (SEDs) display impressive reducing power but, until now, it has not been possible to use them catalytically in radical chain reactions. This is because, following electron transfer, these donors form persistent radical cations that trap substrate‐derived radicals. This paper unlocks a conceptually new approach to super electron donors that overcomes this issue
中性有机超电子给体(SED)显示出令人印象深刻的还原能力,但是直到现在,还不能在自由基链反应中催化使用它们。这是因为在电子转移后,这些供体形成了持久的自由基阳离子,从而捕获了底物衍生的自由基。本文开辟了一种概念性的解决超电子给体的新方法,该方法克服了这个问题,从而导致了第一个催化中性有机超电子给体。
