摘要

我们介绍了利用从脂肪族羧酸中提取的酰基咪唑对富含电子的炔类化合物进行 N-杂环碳烯/有机光氧化协同催化元选择性官能化的方法。与我们之前的工作相比，将所使用的 LED 光的波长从 440 纳米改为 390 纳米可有效促进该反应。

Use of Aliphatic Carboxylic Acid Derivatives for NHC/Photoredox-Catalyzed meta-Selective Acylation of Electron-Rich Arenes

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.
