The invention discloses a preparation method of a 3-sulfonyl-1,2-dihydronaphthalene compound. The method takes methylene cyclopropane compounds and organic sulfonic acid sodium salt as starting materials, and prepares a silver catalyst and an oxidant in a silver catalyst and an oxidant. In the presence of sulfonylation, C-Cσ-bond cleavage and intramolecular cyclization were used to synthesize various 3-sulfonyl-1,2-dihydronaphthalene compounds. The method has the advantages of easily available raw material sources, mild reaction conditions, simple operation, wide adaptability of reaction substrates and high yield. |
