Abstract:
Herein, we report the preparation of silver(I) pentafluorooxosulfate from commercially available AgF and OSF4 . The compound is surprisingly stable in a MeCN solution. Apart from that, AgOSF5 has been stabilised by the addition of 2,2'-bipyridine ligands. Starting from solutions of the unstabilised silver(I) salt, OSF5 complexes with NiII , CuI , and CuII -centres have been obtained. In addition, AgOSF5 has proven to be generally capable of mediating the transfer of OSF5 groups to aryne moieties, thus furnishing a new and safe method for the preparation of OSF5 -substituted arenes. X-ray crystal structure analysis of selected transition-metal OSF5 compounds have revealed distorted octahedral [OSF5 ]- anions which are extensively stabilised by hydrogen bonding.
