Recent progress in direct introduction of fluorinated groups on alkenes and alkynes by means of C-H bond functionalization

Palladium(II)-catalyzed directed trifluoromethylthiolation of unactivated C(sp³)-H bonds

The synthesis of trifluoromethylthiolated aliphatic acid derivatives by Pd-catalyzed C(sp(3))-H bond functionalization was developed. Using a bidentate directing group, the direct and selective introduction of a SCF3 moiety was possible on a range of amides with remarkable selectivity for C(sp(3))-centers with an electrophilic SCF3 source and pivalic acid as an additive. This work constitutes an example of the unactivated C(sp(3))-SCF3 bond formation by C-H activation offering a new access to relevant molecules.

Electrophilic trifluoromethylthiolation of thiols with trifluoromethanesulfenamide

Efficient and highly selective, metal-free, acid promoted synthesis of trifluoromethyl disulfides from thiols and PhNHSCF₃ is described.

First efficient synthesis of SF5-substituted pyrrolidines using 1,3-dipolar cycloaddition of azomethine ylides with pentafluorosulfanyl-substituted acrylic esters and amides

Di-, tri- and tetrasubstituted pentafluorosulfanylated pyrrolidines have been efficiently synthetized via 1,3-dipolar cycloaddition of azomethine ylides.
