설명

일반 설명

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

애플리케이션

Ammonium thiocyanate may be used in the synthesis of the following:

• Substituted 2-aminothiazole derivatives by reacting with -halo ketone carbonyls in the presence of N-methylimidazole.5
• Thiiranes from corresponding oxiranes in the presence of lithium tetrafluoroborate.

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.
