Application
-
Applied in a widely useful, thiosulfate-assisted, synthesis of a variety of diamine-CuCN complexes.
-
Sodium thiosulfate pentahydrate can be used as a sulfur source to synthesize:
Thioester derivatives via one-pot two-step reactions with organic halides and aryl anhydrides.
-
Sulfur nanoparticles using F. benghalensis leaf extract which acts as a reducing and capping agent.
-
Unsymmetrical heteroaryl thioethers via multicomponent reaction with heteroaryl chlorides and alcohols.
-
It can also be used in the fabrication of microencapsulated phase change materials for thermal energy storage applications.
Features
Na2S2O3 5H2O is a low toxic and odorless reagent that can be easily used in large-scale operations.
