The invention discloses a three-phosphine synthesis method, the method is that the diaryl phosphine oxygen, rich electronic aromatic hydrocarbon and the solvent is added in the reaction vessel, and finally adding trifluro anhydride stirring reaction; the temperature of the reaction after the end of the steaming and the solvent is removed, the silica gel column chromatography to obtain the three-phosphine. Compared with the conventional synthesis method, the method of the invention the reaction condition is simple, without any transition metal catalyst, reaction reagent is relatively safe and cheap, the reaction yield is high, good tolerance for the substrate and the like.
