Here we report the synthesis and application of trifluoromethyl thianthrenium triflate (TT-CF3+OTf-) as a novel trifluoromethylating reagent, which is conveniently accessible in a single step from thianthrene and triflic anhydride. We demonstrate the use of TT-CF3+OTf- in electrophilic, radical, and nucleophilic trifluoromethylation reactions.

Fluorine is a highly attractive element for both medicinal chemistry and imaging technologies. To facilitate protein tyrosine phosphatase (PTP)-targeted drug discovery and imaging-guided PTP research on fluorine, several highly potent and 19F MR sensitive PTP inhibitors were discovered through a structure-based focused library strategy.
Organocatalysis approach to trifluoromethylation with fluoroform

The organic base methodology exploits an access to generate the "trifluoromethyl anion" for carbonyl, ester, acid halide, epoxide, deuterium donor, and carbon dioxide substrates to afford the trifluoromethylation products with good overall efficiency even in organocatalysis conditions. The NMR analysis of the mixture of fluoroform and P4-base shows no change thereof. However, on addition of electrophiles, the trifluoromethylation products were obtained efficiently.
