The invention discloses a preparation method of a DiDOPO compound. The preparation method is characterized by comprising the step of reacting by virtue of a ketone compound II and a chlorinated organic phosphine compound III in the presence of an oxygen-containing compound, so as to obtain a compound I. Compared with an existing synthetic method for preparing DiDOPO through reaction of DOPO and aromatic alkyl ketone under the catalysis of phosphorus oxychloride and the like, the preparation method has the advantages that reaction steps are shortened, the cost is effectively lowered, the operability and safety of a process are improved, a product is relatively easily purified, and the yield of the product is relatively high.
