Yadav,Subba Reddy,Subba Reddy,Krishna
, p. 5243 - 5246 (2007)
Ketones possessing α-hydrogens undergo smooth thiocyanation with ammonium thiocyanate in the presence of molecular iodine in refluxing methanol to produce the corresponding α-ketothiocyanates in excellent yields with high selectivity. The use of iodine ma
A simple and efficient thiocyanation of indoles, anilines and keto compounds catalyzed by a polystyrene resin amberlyst-15

, p. 392 - 395 (2010)
Thiocyanation of various aromatic, heteroaromatic and enolizable ketone compounds has been achieved with ammonium thiocyanate in presence of polystyrene cation exchange resin, Amberlyst-15. All the reactions were carried out in acetonitrile at room temper

supporting information, p. 14058 - 14062 (2021/08/16)
Mesoporous graphitic carbon nitride (mpg-C3N4) has been developed as a metal-free heterogeneous photocatalyst for thiocyanation transformations. The reaction proceeds efficiently by utilizing air as a green oxidant under mild reaction conditions, which affords SCN-containing compounds in moderate to excellent yields. Meanwhile, the practicality of this protocol is further demonstrated by the reusability of the mpg-C3N4photocatalyst and the scaled-up reaction. Furthermore, detailed mechanistic studies clearly demonstrate the role of oxygen.

Nan, Guangming,Yue, Huilan
supporting information, p. 1340 - 1345 (2018/05/03)
A simple and convenient visible-light-induced difunctionalization of alkenes with ammonium thiocyanate and dioxygen has been developed at room temperature. A series of α-thiocyanato ketones could be easily and efficiently obtained in moderate to good yields through the formation of C-S and C=O bonds simply by using nontoxic and inexpensive Na 2 -Eosin Y as a photocatalyst.
Allosteric Inhibitors of SHP2 with Therapeutic Potential for Cancer Treatment

, p. 10205 - 10219 (2018/01/10)
SHP2, a cytoplasmic protein-tyrosine phosphatase encoded by the PTPN11 gene, is involved in multiple cell signaling processes including Ras/MAPK and Hippo/YAP pathways. SHP2 has been shown to contribute to the progression of a number of cancer types inclu
One-pot synthesis of (ethoxycarbonyl)difluoromethylthioethers from thiocyanate sodium and ethyl 2-(trimethylsilyl)-2,2-difluoroacetate (TMS-CF2CO2Et)
Xu, Lijun,Wang, Hongyu,Zheng, Changwu,Zhao, Gang
supporting information, p. 6057 - 6066 (2017/09/23)
An efficient one-pot cascade methodology for the synthesis of (ethoxycarbonyl)difluoromethyl thioethers is described. Benzyl, allyl, alkyl halides or diazonium salts as the starting materials together with thiocyanate sodium and TMS-CF2CO2Et in the presence of CsF or NaOAc afford a variety of the fluoroalkylthiolated products in moderate to good yields.
Synthesis of ionic liquid-supported hypervalent iodine reagent and its application as a 'catch and release' reagent for α-substituted acetophenones
Muthyala, Manoj Kumar,Choudhary, Sunita,Kumar, Anil
, p. 14297 - 14303 (2014/04/17)
A novel imidazolium-based ionic liquid-supported hypervalent iodine reagent has been synthesized and employed for a 'catch and release' strategy with substituted acetophenones to generate various α-substituted acetophenones in good to excellent yields. The use of an ionic liquid-supported hypervalent iodine reagent avoids chromatographic separation for the purification of α-substituted acetophenones and thus makes the method greener.

experimental part, p. 1780 - 1785 (2012/05/04)
A very rapid, convenient, and general method for the synthesis of α-oxo thiocyanates has been described by using clay supported ammonium thiocyanate. The procedure avoids the use of additional catalyst, solvent, aqueous work-up and the yields are high. Moreover, the method is applicable for a variety of aryl, heteroaryl, alkyl α-halo carbonyls, β-keto tosylates, α-halo β-dicarbonyl, α-tosyl, β-dicarbonyl, alkyl halide, and alkyl tosylates.
