The sequential transfer hydrogenation/hydrogenolysis of furfural and 5‐hydroxymethylfurfural to 2‐methylfuran and 2,5‐dimethylfuran was studied over in situ reduced, Fe 2 O 3 ‐supported Cu, Ni, and Pd catalysts, with 2‐propanol as hydrogen donor. The remarkable activity of Pd/Fe 2 O 3 in both transfer hydrogenation/hydrogenolysis is attributed to a strong metal–support interaction. Selectivity towards hydrogenation, hydrogenolysis, decarbonylation, and ring‐hydrogenation products is shown to strongly depend on the Pd loading. A significant enhancement in yield to 62 %, of 2‐methylfuran and 2‐methyltetrahydrofuran was observed under continuous flow conditions.
