Abstract

This review focuses on the recent efforts to functionalize dinitrogen via complete cleavage of the N≡N bond with particular emphasis on mid to late transition metal complexes. The relationships of electronic and structural parameters for the most common N2-bonding modes (end-on and side-on bridging) with N2-splitting reactivity are discussed. This analysis points towards electronic configurations with π10 (end-on) and π8δ2 (side-on) electrons within the M2N2-cores for full N–N bond cleavage into terminal and bridging nitride complexes, respectively. The full body of work on N2-splitting with group 6–8 metals is comprehensively presented. Ligand electronic and steric effects are discussed in detail for privileged platforms, such as low coordinate, electron rich complexes with π-donating ligands. Finally, several strategies for functionalization of the nitrides resulting from N2-splitting are presented that lead to N–C bond formation. The developed pseudo-catalytic cycles reported so far that combine N2-cleavage, nitride functionalization, and N-transfer provide guidelines for rational catalyst design.
