The synthesis of the first stable, five-membered N,Nâ²-diamidocarbenes (DACs), including a differentially N-substituted derivative, was achieved via the reduction of a geminal dichloride precursor using potassium. Key differences between the reactivity of the five-membered DACs and their six-membered congeners were observed, including an ability to insert into electron-rich CâH bonds.
首个稳定的五元N,N'-二酰基氨基卡宾(DACs)的合成已成功实现,包括一种不同取代的N-取代衍生物,该合成是通过使用钾还原一个双氯化合物前体完成的。观察到五元DAC与其六元同类化合物在反应性方面的关键差异,包括它能够插入电子丰富的C–H键。
