General and Practical Formation of Thiocyanates from Thiols [PDF]

Chemistry - A European Journal, 2015
A new method for the cyanation of thiols and disulfides using cyanobenziodoxol(on)e hypervalent iodine reagents is described. Both aliphatic and aromatic thiocyanates can be accessed in good yields in a few minutes at room temperature starting from a ...

Straightforward Access to Thiocyanates via Dealkylative Cyanation of Sulfoxides

Organic Letters, 2021
Thiocyanates, versatile building blocks in organic synthesis, are shown to be easily accessible via an interrupted Pummerer reaction of sulfoxides. This facile dealkylative functionalization proceeds under mild conditions through electrophilic activation

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

Journal 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

Thiocyanation of α-amino carbonyl compounds for the synthesis of aromatic thiocyanates

, 2020
A procedure for K2S2O8-mediated thiocyanation of α-amino carbonyl compounds has been developed for the synthesis of aromatic thiocyanates. A series of α-amino carbonyl compounds have been investigated, and the desired products are obtained in 74%–93 ...

Investigations on the Formation of 4-Aminobicyclo[2.2.2]-octanones

Molecules, 2005
Benzylidene acetone reacts with thiocyanates derived from secondary amines in a one-pot reaction to give 4-aminobicyclo[2.2.2]octan-2-ones. The reaction mixture was investigated for the presence of possible intermediates using GC-MS.

Preparation of Arylthiocyanates Using N,N′-Dibromo-N,N′-bis(2,5-dimethylbenzenesulphonyl) ethylenediamine and N,NDibromo-2,5-dimethylbenzenesulphonamide in the Presence of KSCN as a Novel Thiocyanating Reagent

Molecules, 2001
N-Bromosulphonamides, synthesized via direct bromination of sulphonamides, react with several types of arene substrates in the presence of KSCN to afford aryl thiocyanates. The method appears to be generally applicable to benzenoid substrates with a wide
