Reductions of ((organosilyl)amino)(alkylamino)boranes with selected hydrides were studied in order to further clarify the reaction pathway of reactions between LiBH4 and chlorobis(amino)boranes which contained an (organosilyl)amino group. A clear liquid which was identified as a mixture of s-Bu2NBH2 and (Me3Si)2NBH2 was obtained from a reaction between s-Bu2NB(Cl)N(SiMe3)2 and LiBH4. The reaction of s-Bu2NB(H)N(SiMe3)2 with THF·BH3 resulted in the formation of n-BuOB(H)N(SiMe3)2 and s-Bu2NBH2. The compounds s-Bu2NB(Cl)N(SiMe3)2 and s-Bu2NB(H)N(SiMe3)2 were prepared by allowing (Me3Si)2NLi to react with s-Bu2NBCl2 and s-Bu2NBClH, respectively. The compound s-Bu2BClH was isolated from a reaction involving s-Bu2NBCl2 and LiBH4 in a 1:1 mole ratio. In the reaction between s-Bu2NB(Cl)N(H)SiMe3 and LiBH4, s-Bu2NBH2, (Me3Si)2HN3B3H3, and [Me3SiNBH]3 were isolated. The same products were obtained from the reaction of s-Bu2NB(H)N(H)SiMe3 with THF·BH3. However, s-Bu2NBH2, s-Bu2NBClH, and s-Bu2NH2Cl were isolated from the reaction of s-Bu2NB(Cl)N(H)SiMe3 with THF·BH3. The compounds s-Bu2NB(Cl)N(H)SiMe3 and s-Bu2NB(H)N(H)SiMe3 were prepared by allowing (Me3Si)2NH to react with s-Bu2NBCl2 and s-Bu2NBClH, respectively.
