4-sulfur pentafluoride phenol compound, preparing method and preparing method for sulfur pentafluoride substituted benzopyran compound

The invention provides a 4-sulfur pentafluoride phenol compound, a preparing method and a preparing method for a sulfur pentafluoride substituted benzopyran compound. Sulfur pentafluoride phenol is used as a raw material, sulfur pentafluoride sulfur pentafluoride with multiple substituent groups is synthesized through multi-step synthesis, and then the sulfur pentafluoride substituted benzopyran compound is synthesized on the basis. The method is simple and low in cost, has wide industrial application prospects and overcomes the defects that at present, the number of types of sulfur pentafluoride phenol is small, and the requirement for synthesizing various sulfur pentafluoride substituted benzopyran compounds cannot be met.
