unprecedented combination of light and P(III)/P(V) redox cycling for the efficient deoxygenation of aromatic amine N-oxides. Moreover, we discovered that a large variety of aliphatic amine N-oxides can easily be deoxygenated by using only phenylsilane. These practically simple approaches proceed well under metal-free conditions, tolerate many functionalities and are highly chemoselective. Combined experimental
我们在此报告了一种前所未有的光和 P(III)/P(V) 氧化还原循环的组合,用于芳香胺N-氧化物的有效脱氧。此外,我们发现仅使用苯基硅烷就可以轻松地对多种脂肪胺N-氧化物进行脱氧。这些实际上简单的方法在无金属条件下可以很好地进行,耐受许多功能并且具有高度的化学选择性。结合实验和计算研究,能够深入了解控制芳香族和脂肪族胺N-氧化物反应性的因素。
