Osmium(VI) Nitrido Complexes with Perfluorinated Alcoholate Ligands: Expanding Ligand Scope through a Simple Silver Oxide‐Mediated Synthesis Route

Key Points

Stable osmium nitrido complexes were synthesized through a silver oxide-mediated method, yielding good results.
The complexes demonstrated unique coordination with perfluorinated alcoholate ligands, expanding existing ligand scope.
Crystal structures of several complexes were analyzed, highlighting their distinctive O-donor ligand compositions.
These findings suggest potential for further functionalization of osmium nitrido complexes with unique ligands.

Abstract

The coordination of perfluorinated alcohols toward an osmium(VI) nitrido center is described. Herein, NBu 4 OsNCl 4 is reacted with hexafluoroacetone hydrate (HFA), perfluoropinacol (PFP), or pentafluorophenol (C 6 F 5 OH) in the presence of Ag 2 O to obtain the stable complexes NBu 4 Os(N)(O 2 C(CF 3 ) 2 ) 2 ( 1 ), NBu 4 Os(N)(O 2 C 2 (CF 3 ) 4 ) 2 ( 2 ), NBu 4 Os(N)(OC 6 F 5 ) 4 ( 3 ), and NBu 4 Os(N)(Cl) 2 (O 2 C(CF 3 ) 2 ) ( 4 ) in overall good yields. These complexes represent rare examples of Os(VI) nitrido complexes that carry four O ‐donor ligands, as no examples have been reported for perfluorinated alcoholates so far. Complexes 1 and 4 extend the coordination chemistry of the otherwise underrepresented O 2 C(CF 3 ) 2 ligand. The latter offers the potential for further functionalization of the osmium(VI) nitrido complex through substitution of the remaining chloride ligands. The compounds are fully characterized, and the crystal structures of compounds 1 , 2, and 3 are analyzed.
