phenol-formaldehyde condensation products of sodium lignosulfonate and lignocellulose derived aldehydes were first reported as cost-effective catalysts for the hydroxyalkylation/alkylation (HAA) of 2-methylfuran and furfural. Among them, the LF resin...

alternative to precious-metal catalysts for many reactions. Herein, we report that graphene oxide becomes superactive for C–C coupling upon incorporation of a highly oxidized surface associated with Brønstedacidic oxygen functionality and defect sites along the surface and edges. The resulting improved graphene oxide (IGO) demonstrates significantly higher activity over commonly used framework zeolites for
Diesel or jet fuel range branched alkanes were synthesized for the first time by the combination of hydroxyalkylation–alkylation (HAA) of 2-methylfuran with hydroxyacetone and subsequent hydrodeoxygenation. Due to the electron-withdrawing effect of the hydroxyl group, the hydroxyacetone route exhibited evident advantages (higher HAA reactivity and diesel yield) over the previous acetone route.

respective ionic liquids. Among the several preapered ionic liquids, strong acidic imidazolium based butylsulfonic acid (6) showed the best activity with a maximum of 84% yield of condensation product. This strategy offers significantly highyield production of condensation products of furan and furfural as compared to the traditional mineral acid route. The activity and stability of the -SO3H functionalized
