Ionic Liquids for Fast and Solvent-Free Nucleophilic Trifluoromethylthiolation of Alkyl Halides and Alcohols
The trifluoromethylthiogroup is of rising interest in medicinal, agrochemical, and materials chemistry. Although several strategies for the introduction of this functional group have been described, new synthetic methods are needed. A novel ionic liquid, 1-n-butyl-3-methylimidazolium trifluoromethylthiolate, has been developed and is herein reported as an efficient and recyclable in situ generated

reaction of trifluoronitrosomethane with hydroxylamine followed by the treatment with trifluoromethanesulfonyl fluoride in the presence of a base. TNS-Tf was demonstrated to be an effective trifluoromethylatingagent photochemically or thermally for aromatics, thiols, disulfides, and uridine derivatives. The insertion reaction by two trifluoromethyl groups of TNS-Tf to the sulfur-sulfur bonds was observed
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 )3 AgF], which has been isolated in high yield. The thermodynamic stability of the Ag-F bond is shown
