Descripción general
Sodium sulfite is a water-soluble inorganic salt that is commonly used as a reagent for sulfonation and sulfomethylation reactions. Additionally, it is also used as a bleaching, de-sulfurizing, and dechlorinating agent.
Aplicación
Sodium sulfite can be used as:
In combination with carboxylic acids, it forms an effective system for the reductive acylation of aromatic nitro compounds.
- A source of sulfur dioxide (SO2) in the synthesis of 1,4 diazabicyclo[2.2.2]octane bis(sulfur dioxide) (DABSO).
- A reducing agent in the photocatalytic cyclization of 2-isocyanoaryl thioethers to synthesize 2-CF2/CF3-containing benzothiazoles in the presence of Ir-based catalyst.
- A reagent in the selective synthesis of 2-amino-1-iodonaphthalene from 2-naphthylamine in the presence of NaIO3/HCl.
In combination with carboxylic acids, it forms an effective system for the reductive acylation of aromatic nitro compounds.
