Characterization of an FeN–NH2 Intermediate Relevant to Catalytic N2 Reduction to NH3
The ability of certain transition metals to mediate the reduction of N2 to NH3 has attracted
broad interest in the biological and inorganic chemistry communities. Early transition metals
such as Mo and W readily bind N2 and mediate its protonation at one or more N atoms to
furnish M (N x H y) species that can be characterized and, in turn, extrude NH3. By contrast,
the direct protonation of Fe–N2 species to Fe (N x H y) products that can be characterized
has been elusive. Herein, we show that addition of acid at low temperature to [(TPB) Fe …
