A convenient method for the transformation of alcohols into alkyl trifluoromethyl sulfides
Kolomeitsev,Chabanenko,Roschenthaler,Yagupolskii
, p. 145 - 146 (1994)
Alkyl trifluoromethyl sulfides are prepared by phosphitylation of alcohols or α-hydroxy esters using bis(diethylamido)chlorophosphite followed by the reaction with bis(trifluoromethyl) disulfide under extremely mild conditions in near by quantitative yields.
A new simple access to trifluoromethyl thioethers or selenoethers from trifluoromethyl trimethylsilane and disulfides or diselenides
Billard, Thierry,Langlois, Bernard R.
, p. 6865 - 6868 (1996)
Trifluoromethyl thioethers (or selenoethers) are easily obtained in one pot at 0°C from disulfides (or diselenides), commercial trifluoromethyl trimethyl silane and TBAF.

Trifluoromethyl sulfoxides are a new class of trifluoromethylthiolating reagent. The sulfoxides engage in metal-free C?H trifluoromethylthiolation with a range of (hetero)arenes. The method is also applicable to the functionalization of important compound classes, such as ligand derivatives and polyaromatics, and in the late-stage trifluoromethylthiolation of medicines and agrochemicals. The isolation and characterization of a sulfonium salt intermediate supports an interrupted Pummerer reaction mechanism.
Fluoroalkylselenolation of Alkyl Silanes/Trifluoroborates under Metal-Free Visible-Light Photoredox Catalysis

Herein a metal-free fluoroalkylselenolation of alkylsilanes as well as potassium alkyltrifluoroborates under visible light photocatalysis is disclosed. The developed methodologies are performed under mild conditions, room temperature in the presence of an organic photocatalyst and blue LED irradiation. Mechanistic investigations including luminescence and EPR spectroscopy allow us to shed light on both mechanisms.
The First Organosilver(III) Fluoride, [PPh4][(CF3)3AgF]
Joven-Sancho, Daniel,Baya, Miguel,Martín, Antonio,Orduna, Jesús,Menjón, Babil

Organosilver(III) fluoride complexes have been assigned a key role in different fluorination processes. To the best of our knowledge, however, none of them seem to have been isolated or even detected thus far. Here we report on the successful synthesis of the trifluoromethyl derivative [PPh4][(CF3)3AgF], which has been isolated in high yield. The thermodynamic stability of the Ag?F bond is shown by calculation and demonstrated by multistage mass spectrometry (MSn) under collision-induced dissociation (CID) conditions. Nevertheless, the substantial elongation found in the Ag?F bond (X-ray) is correlated with a marked nucleophilic character of the terminal F ligand. This Ag?F bond is, in fact, quite reactive: it suffers hydrolysis and is also solvolyzed by thiols.

Ir(III)-Catalyzed mono-olefination of Aryl C-H Bonds Using -SCF3 as a Weak directing group
Bao, Rui-Peng,Chen, Xian,Li, Chen,Wang, Dong-Hui
supporting information, p. 8116 - 8121 (2019/10/14)
The trifluoromethylthionyl group (-SCF3) is an efficient weak directing group for Ir(III)-catalyzed aryl C-H olefination. Various trifluoromethylthioethers provide high levels of mono-olefination products in good to excellent yields under mild conditions with a 2,2′-bipyridine ligand or AgBF4 as an additive. Mechanistic studies indicate the C-H cleavage is the rate-determining step. The directing group ability of the -SCF3 group is benchmarked against several other weak directing groups by competition experiments under Ir(III)-catalyzed conditions.

Preparation of difluoromethylthioethers through difluoromethylation of disulfides using TMS-CF2H
Howard, Joseph L.,Schotten, Christiane,Alston, Stephen T.,Browne, Duncan L.
supporting information, p. 8448 - 8451 (2016/07/07)
We report an operationally simple, metal-free approach for the late-stage introduction of the important lipophilic hydrogen-bond donor motif, SCF2H. This reaction converts diaryl- and dialkyl-disulfides into the corresponding aryl/alkyl-SCF2H through the nucleophilic transfer of a difluoromethyl group with good functional group tolerance. This method is notable for its use of commercially available TMSCF2H, and does not rely on the need for handling of sensitive metal complexes.
Metal-Free Direct Dehydroxytrifluoromethylthiolation of Alcohols via the Umpolung Reactivity of Trifluoromethanesulfenamides
Glenadel, Quentin,Tlili, Anis,Billard, Thierry
supporting information, p. 1955 - 1957 (2016/04/26)
A direct dehydroxytrifluoromethylthiolation of alcohols with trifluoromethanesulfenamide has been described. This method, based on the original umpolung reactivity of trifluoromethanesulfenamides, proposes a direct "OH-SCF3 exchange" under mild and, more especially, metal-free conditions.
