    Ruthenium-Catalyzed Dehydrogenation of Ammonia Boranes
    摘要:
    The dehydrogenation of ammonia borane (AB) and methylammonia borane (MeAB) is shown to be catalyzed by several Ru-amido complexes. Up to 1 equiv of H-2 (1.0 system wt %) is released from AB by as little as 0.03 mol % Ru within 5 min, and up to 2 equiv of H-2 (3.0 system wt %) are released from MeAB with 0.5 mol % Ru in under 10 min at room temperature, the first equivalent emerging within 10 s. Also, a mixture of AB/MeAB yields up to 3.6 system wt % H-2 within 1 h with 0.1 mol % Ru. Computational studies were performed to elucidate the mechanism of dehydrogenation of AB. Finally, it was shown that alkylamine-boranes can serve as a source of H-2 in the Ru-catalyzed reduction of ketones and imines.

    A highly asymmetric B−H insertion reaction of various diazo compounds with amine‐ and phosphineborane adducts catalyzed by Ru(II)‐Pheox was developed to give chiral organoboranes in high yields (up to 94 %) with high enantioselectivities (up to 98 % ee). It is the first example of a highly enantioselective B−H insertion reaction using a ruthenium catalyst.

    Comparing nitrogen bases having equal steric properties, a linear correlation of BH 3 binding affinity vs. Brønsted acidity was found. This correlation can be used to quickly estimate the BH 3 binding affinity of a substrate if p K a is known. Kinetic studies suggest the ligand exchange to occur as a bimolecular S N 2 reaction unless other nucleophilic species were present in the reaction mixture.
    确定了硼烷配合物与溶液中各种氧、、氮和亲核试剂的配体交换反应的平衡常数,并建立了一个跨越 12 个数量级的结合亲和力尺度。虽然 K eq 对溶剂的依赖性极小,但配体交换速率差异很大。在 THF 和 CDCl 3 中分别观察到最快和最慢的速率。此外,根据起始复合物的稳定性,配体交换率在非常宽的范围内不同。发现 BH 3 的结合对空间因子比质子化更敏感。比较具有相同空间特性的氮碱基,发现 BH 3 结合亲和力与布朗斯台德酸度的线性相关。如果 p K a 已知,则该相关性可用于快速估计底物的 BH 3 结合亲和力。动力学研究表明,除非反应混合物中存在其他亲核物质,否则配体交换会作为双分子 SN 2 反应发生。
