Abstract
PURPOSE: To obtain the title compound useful as an intermediate for medicines or synthesis in high yeild selectively, by bringing an α,β-diol into contact with a palladium or platinum catalyst at a low temperature under oxidizing conditions.
CONSTITUTION: A ≥3C α,β-diol of formula I: (R is alkyl, vinyl, or aromatic group) is brough into contact with a palladium or platinum catalyst in the presence of a molecular oxygen-containing gas at 0W200°C, preferably normal temperature to 150°C, to give an α-keto-alcohol of formula II. The amount of oxygen is 1.5 times that is stoichiometrically required for the reaction. The catalyst may be a metal, however, preferably supported on a carrier, e.g. active carbon, silica, or alumina, and the amount is 0.5W10 wt.% based on the carrier.
