The invention discloses a preparation method of a 2-sulfonyl-1,4-diphenol derivative (I), which belongs to the field of organic chemistry. The method uses benzoquinone, substituted benzoquinone or naphthoquinone, substituted naphthoquinone and substituted sodium sulfinate as raw materials, under the action of NH 4 I, reacts in a methanol solvent to obtain 2-sulfonyl-1,4-diphenol derivative. Compared with the existing synthetic methods, it has the following advantages: (1) The raw materials are cheap and easy to obtain, and the 2-sulfonyl-1,4-diphenol derivatives can be synthesized in one step, and the cost is low; (2) The reaction conditions are mild, and the The reaction is carried out, the yield is high, the operation is convenient, the method is green and environmentally friendly, and is beneficial to industrialized production. It provides a new route for the synthesis of 2-sulfonyl-1,4-diphenol derivatives. |
