Swelling Poly(ionic liquid)s: Synthesis and Application as Quasi-Homogeneous Catalysts in the Reaction of Ethylene Carbonate with Aniline
Homogeneous
catalysts generally show higher catalytic activities,
while heterogeneous catalysts are more easily separated from products.
To combine the advantages of heterogeneous and homogeneous catalysts
has been of great interest for many years. Here, we report a kind
of facilely prepared cross-linked polyÂ(ionic liquid)Âs (PILs) with
swelling property to increase catalytic activities of heterogeneous
catalysts. The swelling ability of PILs was greatly affected by cross-linking
density and chain length of substituents on imidazolium, and the unique
swelling property prompted the nonporous PILs to contact with substrates
sufficiently, enhancing their catalytic activities similar to homogeneous
ionic liquid monomers
