Nuclear magnetic resonance and vibrational spectroscopic data support the existence of liner CNB skeleton in monomeric iminoboranes of the type R 2 CNBR 2 ′ . This allene‐like arrangement of the central moiety of the compounds does not seem to enhance the NB bond strength by interaction of this bond with the vicinal CN bond. Rather, in the case of R′ being a hydrocarbon group, the nature of the NB bond is similar to that found in (monoamino) diorganyl‐boranes, R 2 NBr 2 ′ . Similarly, (CF 3 ) 2 CNB[N(CH 3 ) 2 ] 2 may ve viewed as a trisaminoborane. However, the rigid CNBN 2 unit makes this compound colored and the electronic structure of the species was studied; theoretical and experimental data are in good agreement.
