This article discusses the strategies for N-2 reduction and functionalization using molecular transition metal and actinide complexes, distinguishing between dissociative and associative mechanisms.
Dinitrogen (N-2) is the most abundant gas in Earth's atmosphere, but its inertness hinders its use as a nitrogen source in the biosphere and in industry. Efficient catalysts are hence required to ov. ercome the high kinetic barriers associated to N-2 transformation. In that respect, molecular complexes have demonstrated strong potential to mediate N-2 functionalization reactions under mild conditions while providing a straightforward understanding of the reaction mechanisms. This Review emphasizes the strategies for N-2 reduction and functionalization using molecular transition metal and actinide complexes according to their proposed reaction mechanisms, distinguishing complexes inducing cleavage of the N equivalent to N bond before (dissociative mechanism) or concomitantly with functionalization (associative mechanism). We present here the main examples of stoichiometric and catalytic N-2 functionalization reactions following these strategies.
