We report the synthesis, isolation, and structural characterization of an elusive organobismuth(III) dihydride (Ar*-Bi(III)-H, ). The complex features a bulky and rigid Bu-MFluind ligand that permits complete spectroscopic characterization and SC-XRD. The compound is thermally unstable and decomposes to quantitatively form H and Ar*-Bi(I) in a chemoselective intramolecular process. In addition to H formation, the presence of a Bi-H bond is supported by comparative spectroscopy (NMR and IR) with its deuterated analogue -.
我们报道了一种难以捉摸的有机铋（III）二氢化物（Ar*-Bi(III)-H₂）的合成、分离及结构表征。该配合物具有一个庞大且刚性的Bu-MFluind配体，这使得能够进行完整的光谱表征和单晶X射线衍射分析（SC-XRD）。该化合物热不稳定，在一个化学选择性分子内过程中分解定量生成氢气和Ar*-Bi(I)。除了氢气生成外，通过与氘代类似物（Ar*-Bi(III)-D₂）的对比光谱（核磁共振和红外光谱）也证实了Bi-H键的存在。
