    摘要: A method for manufacturing a ketone, includes oxidizing an internal olefin or a cyclic olefin having a functional group containing a hetero atom and one carbon-carbon double bond or more at a position other than terminals of a molecule thereof in an amide-based solvent in the presence of water, a palladium catalyst, and molecular oxygen, without oxidizing the functional group, thereby bonding an oxo group to at least one of the carbon atoms constituting the carbon-carbon double bond. The amide-based solvent is represented by formula (1): wherein R1 represents an alkyl group having 1 to 4 carbon atoms; R2 and R3 each independently represent an alkyl group having 1 to 4 carbon atoms or an aryl group; and when R1 and R2 are alkyl groups, R1 and R2 may be bonded to each other to form a ring structure.
