Catalytic C-C coupling of furanic platform chemicals to high carbon fuel precursors over supported ionic liquids

Imidazolium-based ionic liquid (IL) catalysts with different anions (Cl-, HSO4-, and CF3SO3-) were covalently anchored to the surface of fibrous silica (FS) by using alkyl chains as a linker. The prepared catalysts were applied for the C-C coupling reactions of 2-methylfuran (2-MF) with levulinic acid (LA), angelica lactone (AL), and ethyl levulinate (EL) to synthesize high carbon fuel precursors. The hydrophilic nature of FS supported IL catalyst having bisulfate anion was suitable for the self C-C coupling reaction of 2-MF and the reaction of 2-MF with LA. FS supported IL catalyst having triflate anion (FS-ILCF3SO3) exhibited high conversion and selectivity for the target fuel precursors from the C-C coupling reaction of 2-MF with AL and EL. The increased solubility, tunable acidity, and hydrophilicity/hydrophobicity of FS-ILHSO4 and FS-ILCF3SO3 promise a sustainable catalyst system. Supported ILs make the transformation processes greener and more efficient for large-scale production of biomass-derived fuel precursors.

The alkylation of 2-methylfuran with mesityl oxide was carried out over a series of solid acid catalysts. Among the investigated candidates, Nafion-212 resin exhibited the highest catalytic efficiency and good stability, which can be rationalized by the h

5-Hydroxymethyl-2-furancarboxaldehyde and 5-chloromethyl-2-furancarboxaldehyde have been reduced electrochemically at 0.2 V (SCE) to 5-methyl-2-furancarboxaldehyde in a two-phase system, the aqueous phase being 6 M hydrochloric acid containing 1 M sodium iodide and the organic phase dichloromethane or dichloromethane (75percent) diethyl ether (25percent).Further reduction (-0.6 to -0.8 V) gave a mixture of 2,5-hexanedione, 1,2-bis(5-methyl-2-furyl)ethene, and bis(5-methyl-2-furyl)methane, together with polymerization products. 2-Furanemethanol could be reduced to 2-methylfuran and 5,5-bis(5-methyl-2-furyl)-2-pentanone.Reaction schemes have been proposed for the formation of these compounds.
