A carbene-stabilized iminocarboranylboron(i) compound has been synthesized and structurally characterized. Single-crystal X-ray analyses and DFT calculations show that the π back donation of the lone pair of electrons on the boron(i) center onto the π* orbital of the imine unit is crucial for removing the electron density of the boron center thereby stabilizing such species, in which the carbene serves solely as a σ donor. This work also demonstrates that imines play a similar role to that of carbenes in the stabilization of low valent boron compounds.
