Snapshots of Complete Nitrogen Atom Transfer from an Iron(IV) Nitrido Complex

Degrees of separation: The extent of nitrogen atom transfer from iron(IV) nitrido complexes to unsaturated substrates is dictated by the supporting tris(carbene)borate ligand. This transfer step can be coupled to a subsequent group transfer reaction, creating a cycle for the synthesis of an unsymmetrical carbodiimide (see scheme).
