    Abstract: Disclosed is a process for the production of an oxygen-containing organic compound by oxidizing an organic compound with molecular oxygen in a liquid phase in the presence both of a catalytic nitrogen-containing cyclic compound and a catalyst including a solid superacid and, supported thereon, a transition metal compound, in which the nitrogen-containing cyclic compound contains, as a ring constituent, a skeleton represented by following Formula (1), wherein X represents an —OR group, and wherein R represents hydrogen atom or a hydroxyl-protecting group. The process gives the oxygen-containing organic compound in a high yield and enables easy recovery and reuse of the catalyst.
