“…In early transition metal chemistry, stoichiometric N 2 functionalisation now includes a range of N-C bond formation reactions, particularly through discoveries by Fryzuk 49 and Chirik. 50,51,52,53,54,55,56 Thus, a current challenge is to make these N-C bond forming reactions catalytic, possibly by using middle (Mo) and late (Fe) transition metals like those described above. Because these reactions can construct value-added chemical compounds, there is significantly more promise for commercialization for fine chemicals than for ammonia synthesis.…”
