A sensitive probe for the formation of the anionic N 2 ‐complexes 1 and 2 upon reaction of [VCl 3 (thf) 3 ] with N 2 , dmpe, and Na is their centeral metal. Thus, the 51 V‐NMR signal of the trans ‐complex 1 is a quintet at δ = − 1123. If the reduction is carried out under 15 N 2 , the individual multiplet components additionally split to triplets, a direct indication of the incorporation of nitrogen in the complex. dmpe = dimethylphosphinoethane.
