Application: | Applied in a widely useful, thiosulfate-assisted, synthesis of a variety of diamine-CuCN complexes. |
Application: | 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. |
