Disilyne with a silicon–silicon triple bond: A new entry to multiple bond chemistry*
نویسنده
چکیده
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 cisand trans-2-butenes and phenylacetylene is also described.
