Electrophilic Trifluoromethylthiolation of Allylsilanes with Trifluoromethanesulfanamide

Organic Letters, 2013
A CH(3)COCl-promoted allylic trifluoromethylthiolation of allylsilanes with trifluoromethanesulfanamide has been described. The method allows for an efficient synthesis of a wide range of allylic trifluoromethylthiolated compounds under mild conditions.

Superacid‐Catalyzed Trifluoromethylthiolation of Aromatic Amines

Angewandte Chemie, 2016
AbstractUpon activation under superacid conditions, functionalized tailor‐made N‐SCF3 sulfenamides served as reagents for the trifluoromethylthiolation of aromatic amines. This method has a broad substrate scope and can be used for the late‐stage functionalization of complex molecules such as alkaloids or steroids.

Trifluoromethylthiolation of 1,3-Dithiane

Phosphorus, Sulfur, and Silicon and the Related Elements, 2006
With a view to synthesize 2-(trifluoromethylthio)-1,3-dithiane (1), 1,3-dithiane (2) was reacted in dry pentane at −78°C under dry N2 with trifluoromethylsulfenyl chloride (3) and was found to furnish the desired compound in poor yields along with ten other compounds.

Copper-Mediated Trifluoromethylthiolation of α-Diazoesters

Organic Letters, 2014
A novel Cu-mediated trifluoromethylthiolation of diazo compounds has been developed that provides a convenient synthetic route for the efficient α-trifluoromethylthiolation of simple esters under mild reaction conditions. The reaction is typically carried out at room temperature, and water could be used to promote the reaction.

Shelf-Stable Electrophilic Reagents for Trifluoromethylthiolation

Accounts of Chemical Research, 2015
Fluorine, which is the most electronegative element and has a small atomic radius, plays a key role in pharmaceutical, agrochemical, and materials sciences. One of the fluoroalkyl groups, the trifluoromethylthio group (CF3S-), has been well-recognized as an important structural motif in the design of lead compounds for new drug discovery because of its

State‐of‐the‐Art in Electrophilic Trifluoromethylthiolation Reagents

Chinese Journal of Chemistry, 2016
AbstractThis work proposed a label‐free, cost‐effective and fairly sensitive electrogenerated chemiluminescence (ECL) strategy for the specific detection of lysozyme based on the hemin/G‐quadruplex hybrid. Gold nanoparticles were spread onto the chitosan thin‐film as substrate to adsorb thiolated captures: a hairpin‐structured DNA, integrating dual ...

Trifluoromethylthiolation of Trimethylsilyl Enol Ethers

Phosphorus, Sulfur, and Silicon and the Related Elements, 2002
The treatment of bis-(1,2-trimethylsilyloxy)-1-cyclobutene, 1-(1-trimethylsilyloxy)cyclpentene and 1-(1-trimethylsilyloxy)cyclohexene with trifluoromethylsulfenyl chloride has been found to furnish trifluoromethylthiolated carbonyl derivatives.
