Non-Heme Iron Complexes Applied to Oxyanion Reduction
Oxyanion contamination poses a significant and growing environmental challenge due to the widespread anthropomorphic release of species such as nitrate, perchlorate, phosphate, and sulfate in groundwater and wastewater. Biological systems can convert these pollutants to environmentally benign or …

Oxyanion reduction in a non-heme iron system
… of the iron(III)-oxo species from the reduction of nitrite. Herein, the reduction of other oxyanions, the halogen and selenium oxyanions and chromate, to furnish the iron(III)-oxo complex was explored. In Chapter 2, the reduction of the halogen oxyanions to form the iron(III)-oxo …

Novel Electron Transfer Systems in Hyperthermophilic Methanogenic and Anaerobic Methanotrophic Archaea: F420-dependent Nitrite Reductase and [Fe-S] Cluster Assembling Thioredoxin
… (NH2OH) as an intermediate. Since the mid-point reduction potential of NO2-/NH4+ pair (E0' = +440 mV) is more positive than that of HSO3-/HS- (E0' = ‒116 mV), we rationalize that if reduced coenzyme F420 (F420H2)-derived electrons are proficient for SO32- reduction, they also will be so for NO2- …

Small molecule activation and reduction using non-heme iron complexes
… to a substrate is explored through the aspatial reduction of an iron-azide complex. Reduction of the azide substrate results in fragmentation to N2 and NH3. The protons necessary to afford ammonia derive directly from the secondary coordination sphere. Isotopic labeling studies confirm the source …
