Owing to its unique properties such as chemical and thermal inertness, SF6 is a substrate of commercial interest.1 This as a consequence resulted in the remarkable increase of SF6 in atmosphere. Using electron rich N-heterocyclic carbenes (NHC) for the reduction of SF6 is a safe and effective method to not only degrade SF6, but also transform it into a deoxyfluorinating reagent.2 Electronically different NHCs were studied to compare their efficiency for reducing or degrading the SF6. N-heterocyclic carbenes are found also very reactive towards SF4 to give a mixture of the same products as obtained in case of SF6. Furthermore, this mixture of products can successfully be used in deoxyfluorination reactions.3 4 Hence SF6 can be selectively degraded to non-volatile and well defined products, which in turn can be employed for C-F bond formation.
