Ionic Liquid-Aqueous Micellar Systems for Sustainable Catalysis
Abstract
The growing interest in ionic liquids (ILs, salts melting below 100 °C) as alternative solvents is mostly caused by the possibility to avoid large volumes of volatile solvents that are always associated with human risk, safety issues and poor environmental performance. However, the comparably high price of pure ILs, as well as their often high viscosity is still a major drawback for their application in synthesis or catalysis. Recently, there has been a tremendous increase of interest in the behavior of ILs in the presence of water. It has already been shown that certain ILs can form surfactant aggregates (micelles) in aqueous solution. In this proposal, we will investigate ionic liquid aggregates in IL-water biphasic systems as a novel and compared to conventional organic solvents safer but yet cost-efficient reaction media for organic and industrial synthesis with particular focus on palladium catalyzed reactions. Micellar catalysis in ionic liquid-water systems could not only dramatically improve conversion and efficiency of a chemical reaction, but might even lead to a new spectrum of reactivity.
