The use of carbon dioxide as a low-cost and inherently renewable C1 building block for the synthesis of value-added fine chemicals is of great importance and has been attracted increasing interest. Especially, development of efficient methods to incorporate carbon dioxide into organic compounds forming robust carbon-carbon bonds is challenging issue. For such reactions, various carboxylation reactions using carbon dioxide as a “carboxyl unit” to synthesize carboxylic acids have been realized recently by using transition-metal complexes to activate carbon dioxide. In those examples, specifically, unsaturated compounds having carbon-carbon multiple bonds, such as alkynes, dienes, allenes, and aromatic compounds, have been used as good substrates. In this review article, transition-metal-promoted or -catalyzed carboxylation reactions of unsaturated compounds using carbon dioxide as the building block of carboxyl group are introduced in a comprehensive manner.
