A novel method for the production of an oxygen-containing organic compound is provided. The production of an oxygen-containing organic compound is attained by oxidizing an olefin, an alcohol, or an aldehyde by catalyzing thereof with a molecular oxygen-containing gas in the presence of a catalyst formed of a polyoxo metalate substituted with a divalent transition metal cation.

Provided are a complex prepared from ammonium salt-containing ligands and having such an equilibrium structural formula that the metal center takes a negative charge of 2 or higher, and a method for preparing polycarbonate via copolymerization of an epoxide compound and carbon dioxide using the complex as a catalyst. When the complex is used as a catalyst for copolymerizing an epoxide compound and carbon dioxide, it shows high activity and high selectivity and provides high-molecular weight polycarbonate, and thus easily applicable to commercial processes. In addition, after forming polycarbonate via carbon dioxide/epoxide copolymerization using the complex as a catalyst, the catalyst may be separately recovered from the copolymer.
