carboxylic acids is of great significance. Among the CO2 fixation methods, multiple carboxylation is one of the challenging subjects. Here we investigated the Cu-catalyzed carboxylation of a variety of boronic acid pinacol esters (C(sp2)–, C(sp3)–, and C(sp)–B compounds) with CO2, which efficiently provided the corresponding products, including aryl, alkenyl, alkyl, and alkynyl carboxylic acids. This carboxylation
CO 2的化学固定受到了广泛的关注。特别是与CO 2催化形成C-C键生成羧酸具有重要意义。在CO 2固定方法中,多重羧化是具有挑战性的课题之一。在这里,我们研究了多种硼酸频哪醇酯(C(sp 2 )–、C(sp 3 )– 和 C(sp)–B 化合物)与 CO 2的 Cu 催化羧化反应,有效地提供了相应的产物,包括芳基、烯基、烷基和炔基羧酸。这种羧化也适用于在稳健的反应条件下产生二元和三元羧酸的多重CO2固定(总共29个实例)。
