Acid to acid: A general method has been developed for the synthesis of biaryl compounds through a decarboxylative cross‐coupling reaction between two different (hetero)aryl carboxylic acids (see scheme). The use of a PdII/PCy3 catalyst enables the cross‐coupling reaction of electronically different or electronically similar aryl carboxylic acids. This method is compatible with substrates having nitro
酸到酸:已开发出一种通过两种不同的(杂)芳基羧酸之间的脱羧交叉偶联反应来合成联芳基化合物的通用方法(请参见方案)。使用Pd II / PCy 3催化剂可实现电子不同或电子相似的芳基羧酸的交叉偶联反应。该方法与具有硝基,氰基,氟,氯,溴,三氟甲基和甲氧基取代基的底物相容。
