Description

Description générale

Ammonium thiocyanate is an ammonium salt commonly used for thiocyanation reaction of organic compounds.

Application

Ammonium thiocyanate (ATC) may be used the synthesis of the following:

• Graphitic carbon nitride.
• Three-dimensional nitrogen and sulfur co-doped graphene frameworks (N/S-GFs).
• Substituted 2-aminothiazole derivatives by reacting with α-halo ketone carbonyls in the presence of N-methylimidazole.
• Thiiranes from corresponding oxiranes in the presence of LiBF₄.
• 1,2,4-triazole-3-thiones by a multi-component reaction with benzohydrazide acid and acid chloride in the absence of solvent.

Applied in the formation of novel two-dimensional Cd-SCN coordination solids with unusual and tailorable, checkerboard- or herringbone-patterned structures these structures are important steps toward technologically useful materials.
