本文报道了一种温和而简单的合成联芳基化合物的方法,该方法是通过在Mg(2,2,6,6-四甲基哌嗪)2·2LiCl的作用下,使(芳烃)Cr(CO)3的C-H键去质子化后直接进行芳基化,然后在钯催化下进行交叉偶联反应。
A mild and straightforward synthesis of biaryls is described that is performed through direct arylation of the C–H bond of (arene)Cr(CO)3upon deprotonation with Mg(2,2,6,6-tetramethylpiperazide)2·2LiCl and subsequent palladium-catalyzed cross-coupling reaction.
