The use of CO₂ as a C1 building block will be of essential importance in the future. In this context the synthesis of cyclic carbonates from epoxides and CO₂ gained great attention recently. These products are valuable compounds in a variety of chemical fields. The development of new catalysts and catalytic systems for this atom-economic, scalable, and industrially relevant reaction is a highly active research field. Over the past 17 years great advances have been made in this area of research. This chapter covers the survey of the important known classes of homogeneous catalysts for the addition of CO₂ to epoxides. Besides pioneering work, recent developments and procedures that allow this transformation under mild reaction conditions (reaction temperatures of ≤100 °C and/or CO₂ pressures of 0.1 MPa) are especially emphasized.

将来，将CO ₂用作C1的基本组成部分将至关重要。在这种情况下，近来由环氧化物和CO ₂合成环状碳酸酯备受关注。这些产品是在各种化学领域中有价值的化合物。针对这种原子经济，可扩展和工业相关的反应，开发新的催化剂和催化体系是一个非常活跃的研究领域。在过去的17年中，该研究领域取得了巨大的进步。本章涵盖对重要重要的已知均相催化剂类别（用于添加CO _{2）的调查}环氧化物。除了开创性的工作，特别强调了允许在温和的反应条件（反应温度≤100°C和/或CO ₂压力为0.1 MPa）下进行该转化的最新进展和程序。
