摘要
酸碱双功能催化剂已被广泛用于一系列 CC 键形成反应。在这些催化剂中,有机酸-碱催化剂因其结构多样性、构象动态性和对映选择性而受到广泛关注。为了防止相互失活,一种简单、有效且多用途的策略是将酸和碱同时附着在载体表面。特别是,有机酸和碱的共同固定不仅能增强协同催化的协同效应,还能通过控制串联催化中中间产物的扩散来提高所需产物的产量,从而显著提高能量和原子效率。在这篇综述中,我们将重点介绍最近针对有机酸和碱的共固定化用于协同催化和串联催化这一广泛主题开展的工作。我们主要关注二氧化硅支撑的有机酸-碱催化剂和聚合物支撑的有机酸-碱催化剂的合成策略。此外,我们还总结并讨论了这些催化剂的结构-活性关系。最后,我们将讨论剩余的问题和前景,以推进共固定酸碱双功能催化剂的合理设计和工程化。
Recent advances in co-immobilization of organic acids and bases for cooperative and tandem catalysis
Acid–base bifunctional catalysts have been extensively used for a series of CC bond formation reactions. Among these catalysts, organic acid–base catalysts have attracted wide attention due to their structural variety, conformational dynamics, and enantioselectivity. To prevent mutual deactivation, a simple, effective, and versatile strategy is the attachment of both acid and base onto the surfaces of supports. In particular, the co-immobilization of organic acids and bases not only enhances synergistic effects in cooperative catalysis but also improves yields to desired products by controlling the diffusion of intermediates in tandem catalysis, leading to significant improvements in energy and atom efficiency. In this review, we highlight recent works addressing the broad topic of the co-immobilization of organic acids and bases for cooperative and tandem catalysis. We mainly focus on the synthetic strategies for silica-supported organic acid–base catalysts and polymer-supported organic acid–base catalysts. Furthermore, we summarize and discuss the structure–activity relationships of these catalysts. Last, the remaining issues and prospects will be discussed to advance the rational design and engineering of co-immobilized acid–base bifunctional catalysts.
期刊介绍:
The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes.
The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods.
The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
