  Stereoselective Synthesis of β-(Chloro)vinylsilanes Using a Regio- and (E)-Stereoselective Bis-Stannylation of Unsymmetrically Substituted Butadiynes:  Application to the Synthesis of a Masked Triyne

  摘要：

  A highly regio- and stereoselective bis-stannylation of unsymmetrically substituted butadiyne 3 provides bis-stannane 4. Selective lithiation of the internal tin residue effects a 1,4-retro-Brook rearrangement to afford vinylsilane 5. This was elaborated into the novel diethynylethene 1, which also functions as a masked triyne.

• β-Chlorovinylsilanes as masked alkynes in oligoyne assembly: synthesis of the first aryl-end-capped dodecayne
  作者：Simon M. E. Simpkins、Michael D. Weller、Liam R. Cox

  DOI：10.1039/b707681a

  日期：——

  An aryl-end-capped dodecayne has been prepared using a four-fold fluoride-mediated dechlorosilylation of a masked dodecayne precursor containing four β-chlorovinylsilane residues that serve as masked alkynes; the unstable dodecayne product has been characterised by UV-vis absorption spectroscopy and ‘matrix-free’ MALDI-TOF mass spectrometry.
