We here report the synthesis of bifunctional catalysts that can be assembled using simple, cheap and accessible building blocks based on resorcinarenes, and their application as efficient, one-component homogeneous catalysts in the coupling of both terminal and internal epoxides with carbon dioxide affording their cyclic carbonate products. Furthermore, a heterogeneous version was also prepared that combines the activity of these bifunctional systems with excellent stability and recycling potential, allowing for a turnover of >1250. This newly prepared organocatalyst obviates the use of any metal, solvent or additives marking it as an attractive catalyst for CO₂ valorization.

聚苯乙烯负载的双功能间苯二碳二烯是廉价，无金属且可回收的环氧化物/ CO ₂偶联反应催化剂

我们在这里报告了可以使用简单，便宜且易于获得的基于间苯二酚的构建基组装的双功能催化剂的合成方法，以及它们作为高效的单组分均相催化剂在末端和内部环氧化物与二氧化碳的偶联中的应用，从而提供了环状碳酸盐产品。此外，还准备了一种异构版本，将这些双功能系统的活性与出色的稳定性和回收潜力相结合，可实现大于1250的周转率。这种新制备的有机催化剂避免了使用任何金属，溶剂或添加剂，将其标记为有吸引力的CO ₂增值催化剂。
