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 acidpinacolesters (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)。
