Method for synthesizing aryl benzyl ether compound
-
Paragraph 0026; 0041, (2021/04/14)
The invention discloses a method for synthesizing aryl benzyl ether compounds, which comprises the following steps: by using an iron (III) complex containing 1, 3-di-tert-butyl imidazole cations and having a molecular formula of [(tBuNCH = CHNtBu) CH] [FeBr4] as a catalyst and di-tert-butyl peroxide as an oxidant, carrying out oxidative coupling reaction on phenolic compounds and toluene compounds to synthesize the corresponding aryl benzyl ether compounds. The method is the first example for preparing the aryl benzyl ether compound through the oxidative coupling reaction of the phenolic compound and the toluene compound, which is realized by an iron-based catalyst, and has the advantages of atom economy, environmental friendliness and good substrate applicability.

Paragraph 0025-0026, (2021/04/26)
The invention discloses an application of an iron (III) complex containing 1,3-di-tert-butyl imidazole cations in synthesis of aryl benzyl ether compounds, and particularly relates to a method for synthesizing corresponding aryl benzyl ether compounds by taking di-tert-butyl peroxide as an oxidizing agent and carrying out oxidative coupling reaction on phenolic compounds and toluene compounds. According to the method, the iron (III) complex is used as the catalyst for the first time, and oxidative coupling of the phenolic compound and the toluene compound is realized. The method is the first oxidative coupling reaction of phenolic compounds and benzyl C(sp3)-H bonds, and a new method is provided for synthesizing aryl benzyl ether compounds. Compared with an existing synthesis method, the method provided by the invention avoids using toxic and polluting halogenated hydrocarbon and strong base, has better atom economy, and conforms to the development concept of green synthetic chemistry.
