PROBLEM TO BE SOLVED: To produce aldehydes or ketones useful for synthesizing medicines or chemically synthesizing an organic material, reduce the amount of a catalyst and further reduce a load on an environment by oxidizing allyl alcohol in the presence of a specific polyphosphoric acid catalyst. SOLUTION: Perillyl alcohol represented by formula I, an alcohol represented by formula III (R<1> and R<2> are each independently H, a 1-10C aliphatic hydrocarbon group or the like; R<3> is H or a 1-4C alkyl) or an alcohol represented by formula V (X is H, a halogen or the like; R<4> is H; R<5> is H or a halogen and R<6> and R<7> are each H or R<4> and R<5> together form a benzene ring; R<6> and R<7> are each H or R4 is H; R<5> is H, a halogen or the like; R<6> and R<7> together form a 5-membered ring) is oxidized in the presence of an arylboron compound catalyst represented by the formula Ar3 B(OH)3-n [Ar is C6 F5 ; (n) is 2 or 3] to respectively provide perillaaldehyde represented by formula II, an unsaturated ketone (anα,β-unsaturated ketone) represented by formula IV or an aromatic ketone represented by formula VI.
