Provided is a method for synthesizing a rare-earth oxo isopropoxide safely with a high yield, using a rare-earth metal, which is more inexpensive than anhydrous rare-earth chlorides, as a raw material. In a solvent containing 90% or more by weight of isopropyl alcohol, a rare-earth metal and isopropyl alcohol are caused to react with each other in the presence of a mercury compound catalyst, a solvent is added thereto or the solvent is partially replaced, and then in a solvent containing 25% or more by weight of an aromatic hydrocarbon solvent having 6 to 10 carbon atoms or a saturated hydrocarbon solvent having 5 to 12 carbon atoms, water is added to conduct partial hydrolysis reaction, thereby synthesizing a rare-earth oxoisopropoxide.
