We describe the use of acyl imidazoles derived from aliphatic carboxylic acids for the N-heterocyclic carbene/organic photoredox co-catalyzed meta-selective functionalization of electron-rich arenes. Compared to our previous work, a change of the wavelength of the applied LED light from 440 nm to 390 nm promotes this reaction efficiently.

使用脂肪族羧酸衍生物进行 NHC/光氧化还原催化富电子芳烃的元选择性酰化

我们描述了使用衍生自脂肪族羧酸的酰基咪唑用于N-杂环卡宾/有机光氧化还原共催化富电子芳烃的间位选择性官能化。与我们之前的工作相比，所应用的 LED 光的波长从 440 nm 变为 390 nm 有效地促进了这种反应。
