Although carbon dioxide is an ideal C1 source, its chemical transformations are not widely developed and are still at a rather low level of maturity industrially. In recent years the development of metal-catalyzed (e.g., Ni, Cu, Rh, Pd, and so on) carboxylation with CO2 as a C1 source has come to represent a potentially powerful method for the preparation of carboxylic acid derivatives. Among these transformations, palladium-catalyzed carboxylation is one of the most widely investigated. This review presents an overview of recent advances in palladium-catalyzed carboxylation with carbon dioxide as a C1 carbon source.

CO2催化钯催化羧化的新进展

尽管二氧化碳是一种理想的 C1 来源，但其化学转化并未得到广泛发展，并且在工业上仍处于相当低的成熟度。近年来，金属催化（例如，Ni、Cu、Rh、Pd 等）以 CO2 作为 C1 源的羧化反应的发展已成为制备羧酸衍生物的潜在有效方法。在这些转化中，钯催化的羧化是研究最广泛的一种。本综述概述了以二氧化碳为 C1 碳源的钯催化羧化反应的最新进展。
