六氟锑酸银研究进展OA

Silver hexafluoroantimonate can activate the Π electron system of alkyne,ketone,carbonyl and other groups,and then generate intramolecular or intermolecular nucleophile reactions.Silver hexafluoroantimonate is a novel compound for complex ring synthesis,coupling reaction and asymmetric reaction.It is a promising catalyst developed on the basis of silver nitrate and silver oxide.Due to its special physical and chemical properties and harsh preparation conditions,silver hexafluoroantimonate was mainly used as a reagent in research and development activities in the past.In recent years,its application field has been expanding,from the early stage as a SbF6-carrier,SbF6-is substituted into the reaction products through the complex decomposition reaction,to the process of organic synthesis as a catalyst or cocatalyst.Market applications are also expanding.In this paper,five synthesis methods of silver hexafluoroantimonate at home and abroad are introduced,and the synthesis method of hexafluoroantimonate containing oxidizer and ion exchange method developed by the author are emphasized,The future research direction is also described.
