Modes of activation of sulfur hexafluoride for the synthesis of sulfur pentafluorides are considered. We report an S‒F activation of sulfur hexafluoride with TEMPO lithium and subsequent reaction with an alkene affording an aliphatic SF5-containing product, which is isolated in low yield and fully characterized. A mechanism involving a single-electron reduction of sulfur hexafluoride, fragmentation to SF5 radical and its addition to alkene is proposed.
