“…1 The synergic effect of both inorganic and organic moieties in these hybrid materials leads to remarkable improvements in catalytic performance in many applications, including acid-base catalysis, chiral transformations, polymerization and selective oxidation. Catalytic reactions that have benefited from this approach include transesterification, 2 Knoevenagel condensation, 3 Sonogashira coupling, 4 the synthesis of cyclic carbonates from CO2 and epoxide, 5 asymmetric epoxidation, 6 hydrogenation, 7 ethylene polymerization, 8 dehydration, 9 and the selective oxidation of sulfides and alcohols. 10 However, whilst catalytically efficient, the instability of many of these hybrid materials limits their widespread application.…”

We report the design of stable, ionic liquid-hybrids, covalently-anchored to the framework architectures of microporous and hierarchical solid supports. The ionic liquid moieties that are anchored to the framework facilitate enhanced mass-transport, and afford superior catalytic performance in the Beckmann rearrangement of cyclic oximes at low-temperatures. The ionic liquid-metal oxide (IL-MO) hybrids also play an important role in modifying the reaction 2 pathway and synergistic enhancements in catalytic properties are attributed to the increased hydrophobicity of the anchored, imidazolium-based ionic liquid.
