The first successful example of cobalt-catalyzed reduction of N2 with Me3SiCl and Na as a reductant, under ambient reaction conditions, gives N(SiMe3)3, which can be readily converted into NH3. In this reaction system, 2,2′-bipyridine (bpy) is found to work as an effective additive to improve substantially the catalytic activity. Co-N2 complexes bearing three Me3Si groups as ancillary ligands are considered to work as key reactive species based on DFT calculations. The DFT results also allow the proposal of a detailed reaction pathway for the transformation of N2 into N(SiMe3)3.
