transient radical generation with the only byproduct being N2. Particularly, this radical process employs traditional carbene precursor diazo esters as the radical source, which is the first case in NHC catalysis. Compared to the previous pathway that produces radicals with large discard fragments, this merged channel possesses great atom economy.
在此,我们报道了在多功能合成子重氮酯存在下,N-杂环卡宾 (NHC) 和光共催化的烯烃烷基酰化反应,为仅副产物 N 2 的瞬时自由基生成提供了新思路。特别是,这种自由基过程采用传统的卡宾前体重氮酯作为自由基源,这是 NHC 催化中的第一个案例。与先前产生具有大丢弃碎片的自由基的途径相比,该合并通道具有出色的原子经济性。
