A carbene-stabilized dithiolene zwitterion () activates ammonia, affording and , through both single-electron transfer (SET) and hydrogen atom transfer (HAT). Reaction products were characterized spectroscopically and by single-crystal X-ray diffraction. The mechanism of the formation of and was probed by experimental and computational methods. This discovery is the first example of metal-free ammonia activation via HAT.
卡宾稳定的二硫烯两性离子 () 通过单电子转移 (SET) 和氢原子转移 (HAT) 同时活化氨,生成 和 。反应产物通过光谱和单晶 X 射线衍射进行了表征。通过实验和计算方法研究了 和 的形成机制。这一发现是首例通过 HAT 实现无金属氨活化的例子。
