Abstract

CO fixation into electron-deficient aromatic C-H bonds proceeds with the combined Brønsted bases LiO--Bu and LiO--Am/CsF/18-crown-6 (-Am = CEtMe) under a CO atmosphere to afford a variety of polyfunctionalized aromatic carboxylic acids.

摘要

在一氧化碳气氛下,将一氧化碳固定到缺电子的芳香C-H键反应是在布朗斯特碱LiO⁻Bu和LiO⁻Am/CsF/18-冠-6(-Am = CEtMe)的共同作用下进行的,以得到各种多官能化的芳香羧酸。
