A facile preparation of ammonium [14C]thiocyanate
Journal of Radioanalytical and Nuclear Chemistry, 2005An attractive and simple method has been developed for the preparation of ammonium [14C]thiocyanate from [14C]thiourea which eliminates the necessity of handling highly hazardous potassium [14C] cyanide. [14C]thiourea was isomerized to ammonium [14C]thiocyanate by heating the aqueous solution of thiourea (12%) in a sealed tube at 160 °C for 24 hours ...

Microbiological Oxidation of Ammonium and Thiocyanate Ions in Soil
Nature, 1951AMMONIUM sulphate1 and sodium thiocyanate2, when perfused through chalked soils neutralized by calcium carbonate, are metabolized by the growth of specific groups of soil microflora on the soil crumb surface to nitrate and ammonium sulphate respectively.

Molecular tunneling dynamics of NH3D+ in ammonium sulfate and ammonium thiocyanate
The Journal of Chemical Physics, 1993The kinetics of NH3D+ rotation in ammonium sulfate and ammonium thiocyanate are measured at low temperature (8–60 K). Infrared hole burning of the N–D stretching bands causes reorientation of the ions among distinct positions relative to the crystal lattice, producing nonequilibrium population distributions.

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 ...

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, 2011Ketones possessing α-hydrogen undergo smooth thiocyanation with ammonium thiocyanate in the presence of N-bromosuccinimide (NBS) at room temperature in acetonitrile under neutral conditions to produce the corresponding α-ketothiocyanates in excellent yields with high selectivity. The use of NBS makes this procedure simple, convenient and cost effective.
