Major routes from sugars to liquid fuels involve furan intermediates. On Pd, 5-hydroxymethylfurfural (HMF) can be hydrogenolyzed to 2,5-dimethylfuran (DMF), which can be further hydrogenated to 2,5-dimethyltetrahydrofuran (DMTHF). Both DMF and DMTHF are promising fuel additives, and their syntheses are of high interest. Here, we investigated HMF conversion in air, under high H2 pressure in autoclave, and in a microwave conditions with different hydrogen sources. Under these conditions, Pd-catalyzed reactions generally led to reduced products of HMF while Ru-catalyzed reactions generally led to oxidized products of HMF. Neither DMF nor DMTHF were observed as products of Ru-catalyzed reactions.
