The sequential transfer hydrogenation/hydrogenolysis of furfural and 5-hydroxymethylfurfural to 2-methylfuran and 2,5-dimethylfuran was studied over in situ reduced, Fe2 O3 -supported Cu, Ni, and Pd catalysts, with 2-propanol as hydrogen donor. The remarkable activity of Pd/Fe2 O3 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.
糠醛和 5-羟甲基糠醛经串联转移加氢/氢解反应生成 2-甲基呋喃和 2,5-二甲基呋喃，在原位还原的 Fe2 O3 负载 Cu、Ni 和 Pd 催化剂上，以 2-丙醇作为氢供体进行了研究。Pd/Fe2 O3 在转移加氢/氢解中均表现出显著的活性，这归因于较强的金属-载体相互作用。加氢、氢解、脱羰和环加氢产物的选择性强烈依赖于 Pd 的负载量。在连续流动条件下，观察到 2-甲基呋喃和 2-甲基四氢呋喃的产率显著提高到 62%。
