A new metal-free oxidative [2+2+1] heteroannulation of 1,7-enynes with thiocyanates for producing thieno[3,4-c]quinolin-4(5H)-ones is presented. This reaction employs benzoylperoxide (BPO) as the oxidant and sodium thiocyanate as the sulfur source to ...

A highly selective and efficient approach for the direct trifluoromethylthiocyanation of alkenes has been developed using trimethylsilyl isothiocyanate (TMSNCS) as the thiocyanating agent and Togni reagent as the CF3 source in the presence of copper(I ...

Diphenylantimony(III) thiocyanate: unusual thiocyanate bridging
Journal of the Chemical Society, Chemical Communications, 1991The thiocyanate group can bond via sulphur or nitrogen or bridge between two centres, but in diphenylantimony thiocyanate, unusual bridging gives antimony atoms coordinated by, respectively, two sulphur atoms, two nitrogen atoms and one atom of each type, allowing development of a curious infinite ‘triangular spiral’ structure in the solid state.

Activation of aryl thiocyanates followed by aryne insertion: access to 1,2-thiobenzonitriles.
Organic Letters, 2015Palladium-catalyzed activation of carbon-sulfur bonds allows aryne insertion into aryl thiocyanates to generate new C-SAr and C-CN bonds in one step.

A mild and efficient method for copper-catalyzed trifluoromethylazidation and trifluoromethylthiocyanation of allenes was explored. A series of CF3-containing allyl azides and thiocyanates were obtained with high yields and good stereoselectivities ...

The Cobalt-Thiocyanate Reaction for the Detection of Cobalt and Thiocyanate [PDF]
Mikrochemie, 1930 1. Alkali-thiocyanate is a sensitive reagent for the detection of cobalt in presence of 40 to 50% acetone. Ferric iron can be made harmless by addition of an excess of fluoride. A procedure has been developed for the application of the reaction as a micro-and macro test for cobalt. Cupric copper gives a sensitive reaction and must be removed.

AbstractIn fresh whole plant tissue thiocyanate was not in a “free” state and to obtain satisfactory thiocyanate values it was necessary to disrupt the tissue thoroughly by homogenisation to permit hydrolysis of the thiocyanate‐containing substance.Rape kale contained about 15 mg thiocyanate/100 g of fresh material, less than half the amounts found in ...
