ability of certain surfactant ionicliquids to reduce the surface tension of aqueous solutions and to aggregate in the form of micelles, even at low concentrations, allowing their use as stabilizing or destabilizing agents in homogeneous polymerization in water/oil emulsions. Within this context, this work aims to verify the possible micellar properties of the ionicliquids. Critical micellar concentration
Carboxylate-Based, Room-Temperature Ionic Liquids as Efficient Media for Palladium-Catalyzed Homocoupling and Sonogashira-Hagihara Reactions of Aryl Halides
phosphane-free, palladium-catalyzed homocoupling reaction of aryl iodides and bromides. The efficient copper and phosphane-free Sonagashira coupling reaction of aryl iodides and bromides is also demonstrated in these ILs. One of the ILs was also phosphorylated and showed high efficiency and recyclability as a medium, and was also used as a ligand for palladium-catalyzed homocoupling and copper-free Sonogashira
羧酸盐是一种易于制备、廉价且稳定的离子液体 (IL),可作为碱、配体、还原剂和介质,用于无磷烷、钯催化的芳基碘化物和溴化物的均偶联反应。在这些离子液体中也证明了芳基碘化物和溴化物的高效无铜和磷烷 Sonagashira 偶联反应。其中一种 ILs 也被磷酸化并显示出作为介质的高效率和可回收性,并且还用作钯催化的芳基碘化物和溴化物的均偶联和无铜 Sonogashira 反应的配体。
