CO2 fixation into electron-deficient aromatic C–H bonds proceeds with the combined Brønsted bases LiO-t-Bu and LiO-t-Am/CsF/18-crown-6 (t-Am = CEtMe2) under a CO2 atmosphere to afford a variety of polyfunctionalized aromatic carboxylic acids.
在 CO 2气氛下,通过组合的布朗斯台德碱 LiO- t -Bu 和 LiO- t -Am/CsF/18-crown-6 ( t -Am = CEtMe 2 ) 将CO 2固定成缺电子芳族 C-H 键以提供多种多官能化芳族羧酸。
