  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.

  2‐dibromodisilenes ((E)‐Ar(Br)SiSi(Br)Ar) with N‐heterocyclic carbenes (NHC) afforded NHC–arylbromosilylene adducts or bromide salts of the corresponding bis‐NHC adducts of the formal arylsilyliumylidene cations ([ArSi:]+). In some cases, an NHC was able to replace a bromide anion in the coordination sphere of the arylbromosilylene–NHC adduct.

  稳定的1,2-二溴二ilenes （（E）-Ar（Br）SiSi（Br）Ar）与N-杂环卡宾（NHC）的反应提供了NHC-芳基溴亚甲硅烷基加合物或相应的双NHC加合物的溴化物盐正式的芳基亚甲硅烷基阳离子（[ArSi：] +）。在某些情况下，NHC能够取代芳基溴代甲硅烷基-NHC加合物的配位区内的溴化物阴离子。
