Abstract
A new method of constructing "ArSCF2CF2Cu" from ArSCu and TMSCF2Br (TMS=trimethylsilyl) has been developed. The cross-coupling reactions of the obtained "ArSCF2CF2Cu" with diverse aryl iodides (Ar'I) provide an efficient access to Ar'CF2CF2SAr. Mechanistic studies demonstrate that the "ArSCF2CF2Cu" species were generated through controllable double difluoromethylene insertions into ArS-Cu bonds rather than the 1,2-addition of ArSCu to tetrafluoroethylene.

Abstract
![]()
The introduction of fluoroalkylthioether groups has attracted
the
attention of the drug-discovery community given the special physicochemical
and pharmacokinetic features they confer to bioactive compounds, yet
these are often limited to standard SCF3 and SCF2H moieties. Herein, two saccharin-based electrophilic reagents have
been disclosed for the incorporation of uncommon SCF2CF2H and SCF2CF3 motifs. Their reactivity
performance, multigram-scale preparation, and divergent derivatization
have been thoroughly investigated with a variety of nucleophiles,
including natural products and pharmaceuticals.

Abstract
The asymmetric synthesis of 2,2-difluorinated tetrahydrofurans was accomplished via enantioselective formal [3+2] cycloaddition catalyzed by palladium. The asymmetric reaction between gem-difluoroalkenes and racemic vinyl epoxides or vinylethylene carbonates resulted in the formation of enantioenriched 2,2-difluorotetrahydrofurans with an enantioselectivity up to 98 %. Notably, the reaction used the readily available (R)-BINAP as the ligand at a low loading and yielded a wide variety of difluorinated products in moderate to high yields. Both chiral diastereomers could be obtained in a single sequence.
