Catalytic N2-to-NH3(or -N2H4) Conversion by Well-Defined Molecular Coordination Complexes

“…Instead, catalytic studies focusing first on Mo and then Fe have played a dominant role in the advance of the field due to many inorganic chemists primarily rooting their explorations in the context of modeling biological nitrogenases. 26,57,171,248,249 With the growing availability of different acid/reducing equivalent cocktails, conditions, and methods for analysis, it has become possible to systematically screen the efficacy of other transition metal systems. As a result, in the last five years exciting examples of N 2 -to-NH 3 conversion catalysis by a number of metals, most of which are not biologically relevant (the exception being V), have been reported.…”

“…304 None of these synthetic catalysts yet feature inorganic sulfide or carbide ligands as are present in the cofactors of nitrogenases, although progress toward this aim has been made. 249,305 As efforts to understand the nature of biological nitrogen fixation continue, the development of catalysts featuring more biologically faithful coordination environments will be of significant interest to further constrain and test the feasibility of mechanistic hypotheses. Such studies should also ultimately consider secondary sphere influences.…”
