氨基硼烷，H(2)BNRR‘，代表单体构筑块，可以通过金属介导法从这些单体构筑新型聚合物材料。通过H(2)BNCy(2)在16电子[CpRu(PR(3))(2)](+)碎片上的配位，探讨了这些化合物与金属中心相互作用的基本能力。与等电子烯给体的侧向结合不同，H(2)BNCy(2)的氨基硼烷取代的单(σ-BH)连接模式被建立，其结合能仅比类似的氮氮配合物大约8kcal m ol(-1).基态结构和交换动力学随膦辅助配体组的变化与B-Hσ*性质的轨道的化学上的显著反键是一致的。
Aminoboranes, H(2)BNRR', represent the monomeric building blocks from which novel polymeric materials can be constructed via metal-mediated processes. The fundamental capabilities of these compounds to interact with metal centers have been probed through the coordination of H(2)BNCy(2) at 16-electron [CpRu(PR(3))(2)](+) fragments. In contrast to the side-on binding of isoelectronic alkene donors, an alternative mono(σ-BH) mode of aminoborane ligation is established for H(2)BNCy(2), with binding energies only ~8 kcal mol(-1) greater than those for analogous dinitrogen complexes. Variations in ground-state structure and exchange dynamics as a function of the phosphine ancillary ligand set are consistent with chemically significant back-bonding into an orbital of B-H σ* character.
