Selective Stepwise Reduction of Nitrate and Nitrite to Dinitrogen or Ammonia.

ABSTRACT: This study reports a method for the selective reduction of NO₃^- and NO₂^- to N₂ or NH₃, extending prior work in our lab where NO₃^- was reduced to NO by [N(afa^Cy)₃Fe]OTf₂ (N(afa^Cy)₃ = tris(5-cyclohexyl-amineazafulvene-2-methyl)amine, OTf = triflate). The first pathway involves the reduction of NO₂^- to N₂, where the NO generated in the initial step is transformed to N₂O by PPh₃ and further reduced to N₂ by the [N(afa^Cy)₃Fe]OTf₂ complex. An alternative pathway showcases the reduction of the bound NO complex, [N(afa^Cy)₃Fe(NO)]^2+</
