Synthesis of ammonium [14C]thiocyanate
Journal of Radioanalytical and Nuclear Chemistry, 2003Ammonium [14C]thiocyanate was prepared from potassium [14C]cyanide with a radiochemical yield of 90%. [14C]hydrocyanic acid, generated from potassium [14C]cyanide by sulphuric acid, reacts with aqueous ammonia and elemental sulphur in the presence of trace amounts of ammonium sulphide to yield ammonium [14C]thiocyanate.

Ammonium Thiocyanate for Detaching Antibodies from Histological Specimens
Biotechnic & Histochemistry, 1991When different antigens must be demonstrated in the same structure, the permanence of former antibodies can lead to false identification of another antigen. The peroxidase-antiperoxidase method was used, followed by the oxygen acceptor ethyl-carbazole.

NBS or DEAD as effective reagents in α-thiocyanation of enolizable ketones with ammonium thiocyanate
Tetrahedron Letters, 2011AbstractIn general, NBS‐promoted thiocyanations give higher yields of α‐thiocyanatoketones and require shorter reaction times compared to DEAD‐promoted thiocyanations.

High Pressure NMR Study of Ammonium Thiocyanate
Journal of the Physical Society of Japan, 1993Wide-line proton NMR spectra of ammonium thiocyanate have been recorded at 77 K as a function of external hydrostatic pressure. Contrary to expectations the line-width and the second moment decrease with the increase of pressure. This, however, is in accordance with the anomalous behaviour observed in other magnetic resonance studies of this compound ...

Thermochemistry of Ammonium Based Ionic Liquids: Thiocyanates—Experiments and Computations
Journal of Solution Chemistry, 2015© Springer Science+Business Media New York 2015. Abstract Molar enthalpies of solution of tetra-n-butylammonium thiocyanate [N(Bu)4][SCN] and tetra-n-pentylammonium thiocyanate [N(Pe)4][SCN] in water were measured by using solution calorimetry. The enthalpy of combustion of [N(Bu)4][SCN] was measured by using rotation bomb combustion calorimetry and ...

Visible-Light-Promoted Aerobic α-Thiocyanation of Carbonyl Compounds with Ammonium Thiocyanate
The Journal of Organic ChemistryIn the present study, we successfully developed an efficient thiocyanation of carbonyl compounds by using low-toxicity and inexpensive ammonium thiocyanate as the thiocyanate source under visible light in air (O2) at room temperature. This unified strategy is very facile for thiocyanation of various carbonyl compound derivatives (β-keto esters, β-keto ...

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2008
Raman spectra of water+N,N-dimethylformamide (DMF) mixtures and their solutions with NaNCS, KNCS and NH(4)NCS were obtained. The bands of nu(CO) stretching, delta(OCN) bending, r(CH(3)) rocking and nu(N-CH)(3)) stretching of the DMF molecule with and without salts were studied.
