PRODUCTION OF ALDEHYDES OR KETONES USING ARYLBORON COMPOUND CATALYST

摘要

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 (R¹ and R² are each independently H, a 1-10C aliphatic hydrocarbon group or the like; R³ is H or a 1-4C alkyl) or an alcohol represented by formula V (X is H, a halogen or the like; R⁴ is H; R⁵ is H or a halogen and R⁶ and R⁷ are each H or R⁴ and R⁵ together form a benzene ring; R⁶ and R⁷ are each H or R₄ is H; R⁵ is H, a halogen or the like; R⁶ and R⁷ together form a 5-membered ring) is oxidized in the presence of an arylboron compound catalyst represented by the formula Ar₃B(OH)_3-n [Ar is C₆F₅; (n) is 2 or 3] to respectively provide perillaaldehyde represented by formula II, an unsaturated ketone (an α,β-unsaturated ketone) represented by formula IV or an aromatic ketone represented by formula VI.;COPYRIGHT: (C)1999,JPO
