Tandem hydrothiocyanation/cyclization of CF3-iminopropargyl alcohols with NaSCN in the presence of AcOH [PDF]

open access: yesBeilstein Journal of Organic Chemistry
The synthesis of trifluoromethylated isothiazolium thiocyanates and 4-thiocyanato-2,5-dihydrofurans is presented through hydrothiocyanation/cyclization of CF3-iminopropargyl alcohols using NaSCN in AcOH/MeCN.

The Enigma of Sponge-Derived Terpenoid Isothiocyanate–Thiocyanate Pairs: A Biosynthetic Proposal [PDF]

open access: yesMarine Drugs
The co-occurrence of rare terpenoid thiocyanates (R-SCN), structurally similar to their more common isothiocyanate isomers (R-NCS), poses an enigma: how does the accepted path, terpenyl cation R+ → R-NC → R-NCS, accommodate R-SCN?

Photochemical Degradation of Cyanides and Thiocyanates from an Industrial Wastewater

open access: yesMolecules, 2019
We have explored the simultaneous degradation of cyanides and thiocyanate present in wastewaters from a cokemaking factory using photoassisted methods under varied illumination conditions (from simulated solar light to UV light).

Photocascade chemoselective controlling of ambident thio(seleno)cyanates with alkenes via catalyst modulation [PDF]

open access: yesNature Communications
Controlling the ambident reactivity of thiocyanates in reaction manifolds has been a long-standing and formidable challenge. We report herein a photoredox strategy for installing thiocyanates and isothiocyanates in a controlled chemoselective fashion by ...

Harnessing coumarin-thio(seleno)cyanate conjugates: potent In vivo antiproliferative agents targeting carbonic anhydrases [PDF]

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry
We synthesised coumarin-based derivatives bearing thio- and selenocyanates to selectively inhibit tumour-associated carbonic anhydrases (CAs) IX and XII and to exert antiproliferative effects on tumour cells. Structural variations included chalcogen atom

Convenient Access to Ferrocene Fused aza-Heterocycles via the Intramolecular Ritter Reaction: Synthesis of Novel Racemic Planar-Chiral 3,4-Dihydroferroceno[c]pyridines and 1H-Ferroceno[c]pyrroles

open access: yesInorganics, 2022
An efficient and easy approach to the synthesis of novel racemic planar-chiral 3,4-dihydroferroceno[c]pyridines and 1H-ferroceno[c]pyrroles via the intramolecular Ritter reaction of 2-ferrocenyl-3,3-dimethylbutan-2-ol with nitriles and thiocyanates in ...

Sorption of phosphates and thiocyanates on isomorphic substituted Mg/Zn-Al-type hydrotalcites [PDF]

open access: yesJournal of the Serbian Chemical Society, 2008
The sorption equilibriums of phosphate and thiocyanate anions on isomorphic substituted Mg/Zn-Al-type hydrotalcites were investigated in this study. Langmuir and Freundlich isotherms were used to interpret the equilibrium data for phosphate. The sorption

Phosphorus pentasulfide mediated conversion of organic thiocyanates to thiols

open access: yesBeilstein Journal of Organic Chemistry, 2017
In this paper we report an efficient and mild procedure for the conversion of organic thiocyanates to thiols in the presence of phosphorus pentasulfide (P2S5) in refluxing toluene.
