Abstract
Abstract Herein, we report the preparation of silver(I) pentafluorooxosulfate from commercially available AgF and OSF 4 . The compound is surprisingly stable in a MeCN solution. Apart from that, AgOSF 5 has been stabilised by the addition of 2,2′‐bipyridine ligands. Starting from solutions of the unstabilised silver(I) salt, OSF 5 complexes with Ni II , Cu I , and Cu II ‐centres have been obtained. In addition, AgOSF 5 has proven to be generally capable of mediating the transfer of OSF 5 groups to aryne moieties, thus furnishing a new and safe method for the preparation of OSF 5 ‐substituted arenes. X‐ray crystal structure analysis of selected transition‐metal OSF 5 compounds have revealed distorted octahedral [OSF 5 ] − anions which are extensively stabilised by hydrogen bonding.
