Method for synthesizing diaryl phosphonate derivatives through acid catalysis

According to the method for synthesizing the diaryl phosphonate derivatives under the catalysis of the acid, organophosphorus is used as a phosphorylation reagent, Lewis acid is used as a catalyst, diaryl alcohol shown in a general formula I and the organophosphorus shown in a general formula I are subjected to phosphorylation reaction to construct C-P bonds in one step, and the diaryl phosphonate derivatives are synthesized. Wherein the feeding molar ratio of the diaryl alcohol as shown in the general formula I to the organic phosphorus as shown in the general formula II is (1: 1)-(1: 3), and the feeding molar ratio of the diaryl alcohol as shown in the general formula I to the lewis acid catalyst is (100: 0)-(100: 20); the feeding molar ratio of the diaryl alcohol shown in the general formula I to the Bronsted acid is (1: 1)-(1: 3). Compared with the prior art, the method has the characteristics of mild reaction conditions, cheap and easily available raw materials, wide substrate application range, high ato
