[Bis(trimethylsilyl) methylene] (diisopropylamino) borane: an Allene-Type N = B = C SystemThe title compound iPr2N=B=C(SiMe3)2 (4) is formed as a storable colourless liquid by the elimination of FSiMe3 from F-(iPr2N)B-C(SiMe3)3 (3) at 520°C. The compounds O=CHPh and Me3SiN3 are added to the B=C bond of 4 to give the [2 + 2] cycloaddition product 5 and the [2 + 3] cycloaddition product 6, respectively. The alkylideneaminoborane 4 crystallizes in the space group P21/n. Perpendicular planes through C2NB and BCSi2 define an allene-type structure with a linear N=B=C skeleton, bond lengths 136.3 (N=B) and 139.1 pm (B=C).
