Notes: Diaza-nido-hexaboranes, a Novel Class of AzaboranesIminoboranes RB ≡ NtBu (R = Me, iPr, tBu) are haloborated by R′BHal2 to give diborylamines Hal — (R)B = N(tBu) = B - (R′) — Hal (1a-d), the dehalogenation of which by Na/K-alloy yields either the novel diaza-nido-hexaboranes tBu2N2B4R2R2 (2a - c, R/R′ = Me/Me, iPr/iPr, tBu/iPr) or the azadiboriridine B2NtBu3 (3d), respectively. Product 2a crystallizes in the space group Cmcm, Z = 4. The N2B4 skeleton of 2a represents the nido-fragment of pentagonal bipyramid with a missing vertex at the base.
