The terminal cadmium hydride compound, [κ-Tism]CdH, which features the tris[(1-isopropylbenzimidazol-2-yl)dimethylsilyl]methyl ligand, may be obtained the reactions of either [κ-Tism]CdN(SiMe) or [Tism]CdOSiPh with PhSiH. The Cd-H bond of [κ-Tism]CdH undergoes (a) metathesis reactions with MeI, MeSiX (X = Cl, Br, I, NCO), and MeSnX (X = Cl, Br, I) to afford the corresponding [Tism]CdX derivative, (b) insertion with CO and CS to afford respectively [Tism]Cd(κ-OCH) and [Tism]Cd(κ-SCH), and (c) hydride abstraction with B(CF) to afford {[Tism]Cd}[HB(CF)] that possesses a rare trigonal monopyramidal geometry for cadmium.
末端氢化镉化合物[κ-Tism]CdH，其具有三[（1-异丙基苯并咪唑-2-基）二甲基甲硅烷基]甲基配体，可通过[κ-Tism]CdN(SiMe)或[Tism]CdOSiPh与PhSiH的反应制得。[κ-Tism]CdH的Cd-H键发生如下反应：(a) 与MeI、MeSiX（X = Cl、Br、I、NCO）和MeSnX（X = Cl、Br、I）进行复分解反应，得到相应的[Tism]CdX衍生物；(b) 与CO和CS插入反应，分别得到[Tism]Cd(κ-OCH)和[Tism]Cd(κ-SCH)；(c) 与B(CF)进行氢化物夺取反应，得到{[Tism]Cd}[HB(CF)]，其镉具有罕见的三角单锥几何构型。
