Description générale

Sodium persulfate, also known as Sodium peroxodisulfate is an inorganic compound and is a water-soluble strong oxidizing agent, that is stable and easy to handle. It is commonly used as an oxidant in organic synthesis reactions such as transition-metal-catalyzed or metal-free reactions. Additionally, it is used as a polymerization initiator and in the synthesis of sulfate radical anions through heat-activated decomposition.

Application

Sodium persulfate can be used as an oxidant:
  • For the radical cyclization cascade reaction of 2-alkynylbenzonitriles and sodium arylsulfinates to synthesize sulfonated indenones.
  • In the silica-supported aluminum chloride-catalyzed Baeyer-Villiger oxidation of cyclic and acyclic ketones to lactones or esters.
It can also be used as an initiator for the polymerization of styrene to synthesize polystyrene.
