Lithium perchlorate-catalyzed regioselective ring-opening of aziridines with potassium thiocyanate

open access: yesTetrahedron Letters, 2005
Aziridines react smoothly with potassium thiocyanate in the presence of a catalytic amount of lithium perchlorate in acetonitrile under mild reaction conditions to afford the corresponding β-aminothiocyanates in high yields and with high regioselectivity.

Inhibition of carbon steel corrosion in 1 M HCl medium by potassium thiocyanate

open access: yesJournal of the Association of Arab Universities for Basic and Applied Sciences, 2014
The effect of potassium thiocyanate (KSCN) on the corrosion of carbon steel (C-steel) in 1M HCl has been investigated in relation to the concentration of the inhibitor by polarization curves, electrochemical impedance spectroscopy and weight loss ...

Crystal structure of the Gramicidin/Potassium thiocyanate complex

Journal of Molecular Biology, 1997
The hydrophobic channel-forming polypeptide gramicidin adopts a left-handed antiparallel double helix conformation with 6.4 residues per turn when in complex with monovalent cation salts in a methanol environment. The crystal structure of the gramicidin/potassium thiocyanate complex (a = 32.06 A, b = 51.80 A, and c = 31.04 A; space group P2(1)2(1)2(1))

Ionic conductivity of crystalline potassium thiocyanate

Journal of Physics C: Solid State Physics, 1971
Studies have been made of the a.c. electrical conductivity of single crystals of potassium thiocyanate in various states of purity between 446 K and room temperature. For all samples there was a marked change in the conductivity on passing through the 'phase' transition at 414 K. The position of this break was independent of the purity of the specimens.

POTASSIUM THIOCYANATE TREATMENT OF HYPERTENSION

Journal of the American Medical Association, 1942
To the Editor:— In the article on fatal poisoning from potassium thiocyanate treatment of hypertension (Russell, W. O., and Stahl, W. C.:The Journal, August 8, p. 1177) certain statements are made which are contrary to our conception of the method of control of thiocyanate medication.

Determination of thiocyanate by potassium bromate

Fresenius' Zeitschrift f�r Analytische Chemie, 1957
Estimation of thiocyanate, based on its titration with standard KBrO3 solution in presence of 1.5–3.0 N hydrochloric acid, is described. The end point is determined either potentiometrically or with methyl orange as indicator.

Lattice vibrational modes in potassium thiocyanate

Journal of Physics and Chemistry of Solids, 1981
Abstract Calculations on long-wavelength lattice vibrations have been made for cystallline KNCS within the framework of the rigid ion model. The short range force constants and effective charges of the ions have been determined from the observed frequencies.
