(Equation Presented) 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.
β-Chlorovinylsilanes as masked alkynes in oligoyne assembly: Synthesis of the first aryl-end-capped dodecayne
Simpkins, Simon M. E.,Weller, Michael D.,Cox, Liam R.
, p. 4035 - 4037 (2008/03/27)
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 charac
