Abstract

Provided are a 4-sulfur pentafluoride phenol compound and a preparation method therefor, and a preparation method for a sulfur pentafluoride substituted benzopyran compound. According to the present invention, sulfur pentafluoride salicylaldehyde with multiple substituent groups is synthesized through a plurality of steps by using sulfur pentafluoride phenol as a raw material, and then the sulfur pentafluoride substituted benzopyran compound is synthesized on this basis. The method is simple and convenient, and low in cost; overcomes the defects that, at present, the number of types of sulfur pentafluoride phenols is small, and the synthesis of various sulfur pentafluoride substituted benzopyran compounds cannot be met; and has wide industrial application prospects.
