Untangling ancillary ligand donation versus locus of oxidation effects on metal nitride reactivity.

ABSTRACT: We detail the relative role of ancillary ligand electron-donating ability in comparison to the locus of oxidation (either metal or ligand) on the electrophilic reactivity of a series of oxidized Mn salen nitride complexes. The electron-donating ability of the ancillary salen ligand was tuned via the para-phenolate substituent (R = CF₃, H, tBu, OⁱPr, NMe₂, NEt₂) in order to have minimal effect on the geometry at the metal center. Through a suite of experimental (electrochemistry, electron paramagnetic resonance spectroscopy, UV-vis-NIR spectroscopy) and theoretical (density functional theory) techniques, we have demonstrated that metal-based oxidation to [Mn^VI(Sal^R)N]⁺ occurs for R = CF_3</
