  Synthesis and Reactions of a Stable 1,2-Diaryl-1,2-dibromodisilene: A Precursor for Substituted Disilenes and a 1,2-Diaryldisilyne

  摘要：

  Synthesis and isolation of the stable diaryldibromodisilene, Bbt (Br)Si =(Br)Bbt, has been accomplished for the first time. The dibromodisilene underewent substitution reactions with organometallic reagents on the low-coordinated silicon atom to afford the corresponding substituted disilenes. Futhermore, the reaction of 1 with t-BuLi afforded the corresponding 1,2-diaryldisilyne, BbtSi SiBbt, the characters of which were revealed by spectroscopic and crystallographic analyses.
