To efficiently oxidize a compound having an adamantine skeleton without using hydrochloric acid liable to corrode an apparatus, or to efficiently oxidize an aromatic compound, while controlling a hydrogenation side reaction.

This invention relates to the method for producing the oxygen-containing compound, comprising oxidizing a hydrocarbon compound with a molecular oxygen-containing oxidizing agent in the coexistence of hydrogen and a catalyst prepared by reducing a catalyst containing an element selected from the elements of the groups 4 to 10 in the new periodic table, such as a platinum/titania catalyst.
