“…Numerous comprehensive articles have highlighted the efficacy of supported ionic liquid phase catalyst (SILPC) in organic synthesis, including porous silica gels or polymer‐based materials, [6] carbon nanotubes, [7] cellulose and Merrifield resin, [8] chitosan [9] and magnetic nanoparticles [10] etc. Among these SILPCs, cellulose‐supported ILs, expressly categorized as being task‐specific ionic liquid catalysts (TSILCs) due to their unique properties such as high tolerance in most aqueous and organic solvents, inexpensiveness, renewability, eco‐friendliness as well as the most abundant bio‐macromolecule in nature [11–14] …”

In present study we have designed and synthesized novel cellulose supported ionic liquid catalyst (CSILC), [Cell@Al2O3(HEPiPY)]DCA and explored its catalytic efficiency for synthesis of novel 11b,12‐dihydro‐6H,13Hbenzo[5,6][1,3]oxazino[3,4‐a]quinazoline‐6,13‐diones by performing the one pot reaction of 2‐(2‐hydroxyaryl)‐2,3‐ dihydroquinazolin‐4(1H)‐one and 1,1‐carbonyl diimidazole (CDI). The catalyst was characterized by diverse analytical techniques viz. Fourier‐Transform Infrared Spectroscopy (FT‐IR), Scanning Electron Microscopy (SEM), Energy Dispersive X‐ray Analysis (EDX) and Thermo Gravimetric Analysis (TGA). The biological activities of synthesized novel derivatives were evaluated along with in silico assessments against the vascular endothelial growth factor receptor‐2 (VEGFR‐2) target, in which the results were considerable. The catalyst exhibited remarkable reusability up to six consecutive runs without considerable loss in the catalytic activity.

“…SILP materials enables the application of fixed-bed technology facilitating a continuous process and facile product separation, and many supports have already been used for SILP catalysis including silica, Merrifield resin, activated carbon, SBA-15, MCM-41, alumina, titania and cellulose. [14][15][16][17][18][19][20][21][22] Rh-complex based SILP catalysts with various ILs, phosphine/phosphite ligands and supports have previously been synthesized, characterized and tested for hydroformylation of olefins with chain lengths C3-C8. [1,2,4,10,[23][24] SILP catalysts for C2 olefin (ethylene) hydroformylation was first reported by us in 2012, and the catalysts were found highly active with TOF values up to 800 h À 1 .…”

Supported ionic liquid-phase (SILP) catalysts with Rh-TPPTS (Rh-tricesium 3,3',3''-phosphanetriyltris(benzenesulfonate)) complexes and the ionic liquid (IL) 1-butyl-3-methylimidazolium octylsulfate ([BMIm][n-C 8 H 17 OSO 3 ] have been prepared with the supports SiO 2 , MCM-41, SBA-15, Al 2 O 3 and ZrO 2 with IL loadings corresponding to 2.5-70 % of the pore volume, characterized and evaluated for continuous, gas-phase hydroformylation of ethylene. The initial pore size of the supports strongly influenced the pore distribution and the optimal IL loading of the SILP catalysts. After IL loading, pore sizes narrowed for the supports with large mesopores (SiO 2 , SBA-15 and Al 2 O 3 ), while the pore system altered to form secondary larger pores for the support with micropores and small mesopores (MCM-41 and ZrO 2 ). For hydroformylation of ethylene, the amount of IL had an important role on the catalytic activity of the SILP catalysts, and each support exhibited a different optimal IL loading to obtain the highest activity.

The use of solid catalysts to promote organic reactions in water faces the inherent difficulty of the poor mass-transfer efficiency of organic substances in water, which is often responsible for insufficient reaction and low yields. To solve this problem, the solid surface can be manipulated to become amphiphilic. However, the introduction of surfactant-like moieties onto the surface of silica-based materials is not easy. By using an accessible dihydropyran derivative as a grafting linker, a surfactant-combined bifunctional silica-based solid catalyst that possessed an ionic liquid tail and a metal acetylacetonate moiety was prepared through a mild Lewis-acid-catalyzed ring-opening reaction with a thiol-functionalized silica. The surfactant-combined silica-supported metal acetylacetone catalysts displayed excellent catalytic activity in water for a range of reactions. The solid catalyst was also shown to be recyclable, and was reused several times without significant loss in activity.
