Reactions of boron hydrides with the iminium salt [Me2NCH2]I. Synthesis and characterization of 1-X-μ-(Me2NCH2)B5H7 (X = H, C2H5, Br), a new class of bridge-substituted pentaborane derivatives

Reactions of [Me2NCH2]I (1) with salts of the B5H8-, 1-(C2H5)B5H7-, and 1-BrB5H7- anions produce the μ-((dimethylamino)methyl)pentaborane derivatives μ-(Me2NCH2)B5H8, 1-(C2H5)-μ-(Me2NCH2)B 5H7, and 1-Br-μ-(Me2NCH2)B5H7, respectively, in good yields. A structure for these compounds is proposed in which a bridging hydrogen atom of B5H9 has been replaced by a C-N two-atom bridge, the Me2NCH2 group. These clusters are analogues of the arachno-B5H10- anion, and there is no evidence of direct bonding between the Me2NCH2-bridged boron atoms. Reaction of 1 with NaBH4 forms Me3N·BH3, while reaction with [Me4N][B3H8] produces a variety of products including Me3N·BH3, Me3N·B3H7, B2H6, and B5H9. Attack of 1 on B5H9 occurs slowly at 65°C, forming Me3N·BH3 and Me3N·B3H7.
