A protocol for the fast and selective two-electron reduction of the potent greenhouse gas sulfur hexafluoride (SF6) by organic electron donors at ambient temperature has been developed. The reaction yields solid ion pairs consisting of donor dications and SF5-anions which can be effectively used in fluorination reactions.

We thank Dr Christoph Rauber for low temperature 19F-NMR spectra measurements. We would also like to thank Professor A. C. Filippou and Dr J. Tirree for the opportunity to record solid state IR spectra under an inert atmosphere.
