A nitrogen center was abstracted from a pyrrolyl ring to form the dinuclear nitrido‐ and dienyl‐bridged complex 1 during the reaction of [{(tmeda)Nb II Cl} 2 ( μ ‐Cl) 3 Li(tmeda)] with the lithium salt of 2,5‐dimethylpyrrole (tmeda= N , N , N ′, N ′‐tetramethylethylenediamine). A second product from this reaction is the amido‐carbene‐hydride niobium complex 2 , which likewise forms under C−N bond cleavage.
