Abstract

A stable 3,5-diphenyl-1,2-disilabenzene was selectively synthesized by the reaction between the isolable disilyne TbbSi [triple bond, length as m-dash] 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 TbbSiSiTbb and acetylene. Moreover, a plausible formation mechanism for this reaction is discussed.
