Transformation of carbon dioxide (CO₂) into value-added organic compounds is a very important and hot research topic in green and sustainable chemistry because this greenhouse gas is a plentiful, nontoxic, nonflammable and renewable C1 feedstock. Among the various CO₂ fixation reactions, carboxylative cycloaddition of CO₂ into propargylic alcohols represents one of the most beautiful and attractive research topics in the field, since it offers the possibility for the fabrication of synthetically and biologically important five-membered cyclic carbonates from the simple and easily accessible starting materials in one step with 100 % atom economy. This review aims to give a comprehensive overview of the titled CO₂-fixation reactions, with particular emphasis on the mechanistic features of the reactions. The metal-catalyzed transformations are covered first. This is followed by ionic liquid and organocatalyzed reactions. Finally, the only reported example for electrochemically catalyzed reactions will be discussed at the end of this review.

将二氧化碳（CO ₂）转化为增值有机化合物是绿色和可持续化学领域中非常重要且热门的研究主题，因为这种温室气体是大量，无毒，不可燃和可再生的C1原料。在各种CO ₂固定反应中，将CO ₂羧基环化成炔丙基醇代表了该领域最美丽，最有吸引力的研究主题之一，因为它为从碳纳米管制备合成和生物学上重要的五元环状碳酸酯提供了可能性。一种简单易用的原材料，一步一步实现100％的原子经济性。这篇综述旨在对标题为CO _2的内容进行全面概述-固定反应，特别强调反应的机理特征。首先介绍了金属催化的转化。随后是离子液体和有机催化反应。最后，在本综述的最后将讨论唯一报道的电化学催化反应的实例。
