Ir-catalyzed (20 °C) or thermal (70 °C) dehydrocoupling of the linear diborazane MeNH(2)-BH(2)-NHMe-BH(3) led to the formation of poly- or oligoaminoboranes MeNH-BH(2) (x = 3 to >1000) via an initial redistribution process that forms MeNH(2)·BH(3) and also transient MeNH═BH(2), which exists in the predominantly metal-bound and free forms, respectively. Studies of analogous chemistry led to the discovery of metal-free hydrogenation of the B═N bond in the "model" aminoborane iPr(2)N═BH(2) to give iPr(2)NH·BH(3) upon treatment with the diborazane Me(3)N-BH(2)-NHMe-BH(3) or amine-boranes RR'NH·BH(3) (R, R' = H or Me).
Ir 催化（20°C）或热（70°C）去脱氢偶联线性二硼烷 MeNH(2)-BH(2)-NHMe-BH(3)导致多或寡氨基硼烷 MeNH-BH(2)（x = 3 到>1000）的形成，通过初始重分配过程形成 MeNH(2)·BH(3)和瞬态 MeNH═BH(2)，它们分别以主要的金属结合和游离形式存在。类似化学的研究导致在“模型”氨基硼烷 iPr(2)N═BH(2)中发现了 B═N 键的无金属加氢，在与二硼烷 Me(3)N-BH(2)-NHMe-BH(3)或胺硼烷 RR'NH·BH(3)（R，R'= H 或 Me）处理后得到 iPr(2)NH·BH(3)。
