水被认为是最可持续和最安全的溶剂。胶束催化是水中化学的重要贡献者。它促进了涉及水敏中间体和胶束屏蔽效应下的瞬态催化物种的途径，同时也取代了昂贵的配体和偶极非质子溶剂。然而，有一个关键的信息缺乏胶束催化。这包括为什么它在有机溶剂中比传统催化更好，为什么胶束催化的具体规则不同于传统催化，以及未来如何解决胶束催化的局限性。这个观点的目的是突出目前的差距，在我们的理解胶束催化，并提供了一个分析设计表面活性剂的起源和基本组成部分。这也将提供胶束催化的基本理解，包括如何水胶束可以同时执行多种功能，如溶剂，配体和反应促进剂。
Water is considered to be the most sustainable and safest solvent. Micellar catalysis is a significant contributor to the chemistry in water. It promotes pathways involving water-sensitive intermediates and transient catalytic species under micelles’ shielding effect while also replacing costly ligands and dipolar-aprotic solvents. However, there is a lack of critical information about micellar catalysis. This includes why it works better than traditional catalysis in organic solvents, why specific rules in micellar catalysis differ from those of conventional catalysis, and how the limitations of micellar catalysis can be addressed in the future. This Perspective aims to highlight the current gaps in our understanding of micellar catalysis and provide an analysis of designer surfactants’ origin and essential components. This will also provide a fundamental understanding of micellar catalysis, including how aqueous micelles can simultaneously perform multiple functions such as solvent, ligand, and reaction promoter.
