Paragraph 0112-0114, (2021/07/31)
The invention discloses a green synthesis method for synthesizing a diaryl sulfone compound by catalyzing three components of aryl triazene, DABCO (SO2) 2 and beta-naphthol through an iron-containing Lewis acidic ionic liquid through a one-pot method. Under the condition of 90 DEG C, an iron-containing Lewis acidic ionic liquid is used as a catalyst, aryl triazene is used as an aryl source, and DABCO (SO2) 2 is used as an SO2 source, so that the sulfonylation reaction of the C1 site of beta-naphthol is realized. The method has the advantages that the reaction is green, the operation is simple, and no additive is added; raw materials are cheap, easy to obtain, wide in source, simple to prepare and stable in structure; and the used catalyst is cheap and easily available iron ion-containing liquid, and has the advantages of simple preparation, low price, stable structure, small pollution, greenness, environmental protection and the like.
