The invention provides a method for preparing aromatic ring thiophthene-1,1-dioxide. The method comprises the following steps: carrying out one-step cyclization on an ortho-position substituted aromatic ring and sodium alkylsulfinate, and carrying out a dehydration reaction, thereby obtaining the aromatic ring thiophthene-1,1-dioxide. The ortho-position substituted aromatic ring is of a structureof a compound of formula (I) as shown in the description. Compared with synthesis routes of a conventional method, the method for preparing the aromatic ring thiophthene-1,1-dioxide, which is providedby the invention, is easy in raw material obtaining, low in cost, gentle in reaction, easy to control, small in waste generation, small in pollution, simple in aftertreatment and in addition applicable to preparation of all types of aromatic ring thiophthene-1,1-dioxide, novel strategies are provided for the aromatic ring thiophthene-1,1-dioxide, and high production and application values can bemade.
