通过可分离的二硅炔TbbSi=SiTbb（Tbb = 2，6-[CH（SiMe 3）（2）]（2）-4-t-Bu-苯基）与苯乙炔反应，选择性地合成了稳定的3，5-二苯基-1，2-二硅苯。它的分子结构和物理性能进行了检查，并比较那些的1，2-二硅杂苯，是从TbbSi？SiTbb和乙炔。此外，该反应的一个合理的形成机制进行了讨论。
A stable 3,5-diphenyl-1,2-disilabenzene was selectively synthesized by the reaction between the isolable disilyne TbbSi=SiTbb (Tbb = 2,6-[CH(SiMe3)(2)](2)-4-t-Bu-phenyl) with phenylacetylenes. Its molecular structure and physical properties were examined and compared to those of the 1,2-disilabenzene that was obtained from the reaction between TbbSi?SiTbb and acetylene. Moreover, a plausible formation mechanism for this reaction is discussed.
