Stoichiometric reduction of N 2 at a Mo center stabilized by a bulky tetradentate phosphine ligand ( ${{\rm PP}{{{\rm Cy}\hfill \atop 3\hfill}}}$ ) allowed isolation of Mo–imidoamine and Mo–imido complexes. Both complexes as well as the Mo II precursor are equally suitable catalysts for the synthesis of NTMS 3 (TMS=trimethylsilyl) from N 2 , TMSCl, and electron sources. Mechanistic studies prove the involvement of a TMS radical at least in one of the catalytic steps.
