Stepwise Nitrate → Dinitrogen Transformation Mediated by a Series of Synthetic Heme/Cobalt and Heme/Copper Assemblies: Modeling Denitrification with Cytochrome <i>c</i> Oxidase Mimics.

ABSTRACT: Nitrogen oxides (NO _x ) and their reductive transformation pathways (NO₃ ^-→NO₂ ^-→NO→N₂O→N₂) have been implicated in a medley of important physiological, pathological, ecological, and environmental processes. Nature involves disparate enzymatic platforms to perform such NO₃ ^-→N₂ transformations; however, their mechanistic details remain enigmatic to date. Moreover, synthetic models to mimic such stepwise NO₃ ^-→N₂ processes are extremely scarce. Herein, we have employed a series of heme/nonheme (Co/Cu/Zn) assemblies that can efficiently and stoichiometrically reduce NO₃ ^-→NO₂ ^- and eventually produce
