We describe the first thiourea-catalyzed C-F bond activation. The use of a thiourea catalyst and Ti(OiPr)4 as a fluoride scavenger allows the amination of benzylic fluorides to proceed in moderate to excellent yields. Preliminary results with S- and

Herein, we report a highly regioselective gold-catalyzed formal hydration of propargylic gem-difluorides. Not only does this transformation provide access to versatile fluorinated building blocks that were difficult or hardly possible to access befor

Substituted alkenyl aryl tetrafluoro-λ(6) -sulfanes have been prepared by the direct addition of readily accessible chlorotetrafluorosulfanyl arenes to primary alkynes. Substitution of an apical fluorine of the pentafluorosulfanyl group enables modu

The diastereotopic nature of geminal protons γ to the pentafluorosulfanyl (SF 5 ) group was investigated by computational modeling and experimental methods. 1D and 2D NMR techniques were employed to determine the vicinal coupling constants used in t

A facile preparation of aliphatic 2-pentafluorosulfanyl aldehydes is described. To investigate the utility of the aldehydes as synthetic building blocks, various transformations of the aldehydes were explored. The pentafluorosulfanyl group was stable
