弱相互作用调控表面活性剂自组装(Ⅵ)——在催化方面的应用

Self-assembly of surfactants controlled by weak interactions (Ⅵ) Applications in catalysis

表面活性剂在溶液中达到一定浓度后,会形成多种结构、形态不同的有序分子聚集体。介绍了有序分子聚集体作为简单、经济、绿色的反应介质在化学反应中的作用。重点阐述了胶束、反胶束、囊泡和微乳液等聚集体如何参与形成碳-碳键、碳-杂原子键的反应、Keep消除反应以及羟醛反应,并探讨了光致变色的表面活性剂对偶联反应中催化剂的选择性和循环性的影响。

When the surfactant solution reaches a certain concentration, a variety of ordered molecular aggregates with different structures and shapes can be formed. In this paper, the role of ordered molecular aggregates as a simple, economical and green reaction medium in the chemical reaction has been described. We focus on how aggregates such as micelles, reverse micelles, vesicles and microemulsions participate in the reactions involving carbon-carbon/carbon-heteroatom bond formation, Keep elimination reaction and aldol reaction. The effects of the photochromism surfactant on the selectivity and cycling of the catalyst in the coupling reaction are also discussed.
