Reversible ionic liquids are a novel class of solvents that combine an effective medium where reactions occur with a 'built-in' separation ability for facile recovery of the products and catalysts, making the solvent available for recycle. We report the utility of these solvents in a number of reactions (Claisen-Schmidt condensation, Heck C-C coupling, and CO2 capture) and discuss the effectiveness of the separation. We also provide insight into the challenges and limitations of using these unique solvent systems to couple reactions and separations.
ESTER-FUNCTIONAL SILANES AND THE PREPARATION AND USE THEREOF;AND USE OF IMINIUM COMPOUNDS AS PHASE TRANSFER CATALYSTS
-
Paragraph 0094, (2013/06/27)
A method for producing a reaction product comprising an ester-functional silane, the method comprising: i) reacting a composition comprising: a) a haloorganosilane, b) a metal salt of a carboxy-functional compound, c) a phase transfer catalyst comprising a bicyclic amidine, an iminium compound, or a mixture thereof, provided that the iminium compound is not an acyclic guanidinium compound or pyridinium compound, and d) a co-catalyst, provided that the co-catalyst is optional when the phase transfer catalyst comprises the iminium compound.
