Abstract
The process for preparing the carbonyl compound involves oxidizing the olefins in the presence of the catalyst composed of the palladium compound and the polyoxoanion compound in a mixture of water with a cyclic ether having at least a dioxane ring or a dioxolan ring or in the presence of the catalyst composed of the palladium compound, the polyoxoanion compound and the quinone and/or the aromatic diol in a solvent. This process yields carbonyl compounds, such as ketones and aldehydes, useful as solvents, raw chemicals and so on, with a high production rate per unit time and unit palladium quantity.
