trifluoromethanesulfinates to trifluoromethanesulfones (“triflones”) was developed as a synthetic method for obtaining these compounds Their utility as reagents for the construction of carbon skeletons is explored with regard to reactions such as alkylation, conjugation addition, and cycloaddition. In addition, the conversion of triflones to more common functionality is described.

A mechanism study for Pd(II)-catalyzed C(sp3)–H activation using a self-cleaving chlorotetrafluoroethylsulfinyl (−SOCF2CF2Cl) auxiliary as a directing group is reported. Mechanistic studies reveal that (1) the auxiliary group is crucial for C(sp3)–H activation, (2) the reaction undergoes a C(sp3)–H olefination–Michael addition–removal of the auxiliary sequence, (3) the removal of the auxiliary (SORf)
