The biological reduction of N2 to give NH3 may occur by one of two predominant pathways
in which nitrogenous N x H y intermediates, including hydrazine (N2H4), diazene (N2H2) …

Living systems carry out the reduction of N2 to ammonia (NH3) through a series of
protonation and electron transfer steps under ambient conditions using the enzyme …

Biological N2 fixation to NH3 may proceed at one or more Fe sites in the active-site cofactors
of nitrogenases. Modeling individual e–/H+ transfer steps of iron-ligated N2 in well-defined …

We recently reported a reaction sequence that activates C–H bonds in simple arenes as well
as the N–N triple bond in N2, delivering the aryl group to N2 to form a new N–C bond …

Terminal iron nitrides (Fe N) have been proposed as intermediates of (bio) catalytic
nitrogen fixation, yet experimental evidence to support this hypothesis has been lacking. In …

While recent spectroscopic studies have established the presence of an interstitial carbon
atom at the center of the iron–molybdenum cofactor (FeMoco) of MoFe-nitrogenase, its role …

Whereas synthetically catalyzed nitrogen reduction (N2R) to produce ammonia is widely
studied, catalysis to instead produce hydrazine (N2H4) has received less attention despite …

The six-electron oxidation of two nitrides to N2 is a key step of ammonia synthesis and
decomposition reactions on surfaces. In molecular complexes, nitride coupling has been …

Although nitrogenase enzymes routinely convert molecular nitrogen into ammonia under
ambient temperature and pressure, this reaction is currently carried out industrially using the …

The reduction of nitrogen (N2) to ammonia (NH3) is a requisite transformation for life.
Although it is widely appreciated that the iron-rich cofactors of nitrogenase enzymes facilitate …
