说明

一般描述

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
 

应用

应用于广泛使用的、硫代硫酸盐辅助的各种二胺-CuCN配合物合成。[1]
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.

特点和优势

Sodium thiosulfate is:
  • Stable
  • Environmentally friendly
  • Odorless
  • Inexpensive.
