Description

Description générale

Sodium thiosulfate is an inorganic salt composed of thiosulfate and sodium ion with the chemical formula Na₂S₂O₃. It is general reducing agent and useful sulfur source in synthetic chemistry

Application

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

Sodium thiosulfate can be used as a

• Component in the synthesis of unsymmetrical aryl sulfides under aqueous conditions, where C–S–C bond formed in presence of other two components (alcohols and organohalides).
• Reagent for the activation of carbon material.
• Reagent in the synthesis of S-glycosyl thiosulfates (glycosyl bunte salts) by direct condensation of unprotected sugars using dehydrating agent DMC (2-chloro-1,3-dimethylimidazolinium chloride) in water-acetonitrile solvent mixture.
• Reagent with alkyl halide in the synthesis of Bunte salts by SN₂ mechanism using Cu catalyst.
• Reagent in the synthesis of aryl thiols from aryl halides by palladium catalyzed cross-coupling reaction.

Caractéristiques et avantages

Sodium thiosulfate is:

• Stable
• Environmentally friendly
• Odorless
• Inexpensive.
