The search for new oxidizing agents is an interdisciplinary theme.1 We have been developing new highly oxidized and highly oxidizing inorganic complexes by utilizing oxidation-resistant polyanionic chelating (PAC) ligands.2-6 As part of this work, we sought to incorporate multiply bonded nitrogen ligands7 in the same coordination sphere as PAC ligands and discovered that organic azides react in several ways with the osmium(IV) complex trans-Os(η4-HBA-B)(PPh3)2 (1) (Scheme I), depending upon the nature of the azide. Here we report a thermal C-H bond activation via a putative osmium(VIII) bis(imido) complex and the synthesis of a nitrido complex derived from methyl or trimethylsilyl azide.
