| description |
Ionic liquids based on laurylsulfates and tosylates anions were developed and characterized. A Heck reaction (synthesis of trans-ethylcinnamate) was optimized in 1-butyl-3-methyl-imidazolium-tosylate ionic liquid. The recycling of the reaction medium, including the catalyst and
the ionic liquid, was carefully studied and the following results were obtained: eleven reactions were performed without further catalyst additions, the average yield was 85% with an average reaction time of 10 h.
