本文报道了一种硅-硅三重键化合物--含两个双[双（三甲基硅基）甲基]异丙基硅基取代基的二硅炔的合成、晶体结构和表征。从光谱结果和理论计算的角度讨论了sp杂化硅原子的性质。还描述了二硅炔与碱金属、tBuLi和π键合化合物（如顺式和反式-2-丁烯和苯乙炔）的反应性。
Abstract The synthesis, crystal structure, and characterization of a silicon-silicon triply bonded species, disilyne with two bis[bis(trimethylsilyl)methyl]isopropylsilyl substituents, are described. The nature of the sp-hybridized silicon atoms is discussed from the viewpoint of spectroscopic results and theoretical calculations. The reactivity of the disilyne with alkali metals, tBuLi, and π-bonded compounds such as cis- and trans-2-butenes and phenylacetylene is also described.
