General procedure: Furfuryl alcohol (1 mmol, 98 mg), Toluene (5 mL) was added, and Ru / Al 2 O 3 (Wako Pure Chemical Industries, Ltd.) (5 mol% Ru) was suspended.A gas collecting bag filled with oxygen gas was attached,The interior of the reaction vessel was replaced with oxygen using an aspirator.The reaction solution was reacted at 80 ° C. for 24 hours with vigorous stirring, then the catalyst was removed by filtration, and the mother liquor was distilled off under reduced pressure.As a result of analyzing the obtained product, the raw material completely disappeared and the yield of the objective furfural was 98%.In addition, no by-products insoluble in the solvent were produced.
