Alkenylsilane Cross-Coupling Agent

The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.

1-Bromovinyltrimethylsilane; α-Bromovinyltrimethylsilane
  • Useful for cross-coupling to 1-substituted vinylsilanes
  • Employed in cyclopentene annulations
  • Starting material for preparation of ?-trimethylsilylvinylketone
  • Starting material for preparation of trisubstituted olefins
  • Potential for cross-coupling protocols to yield ?-substituted vinylsilanes
  • Reacts with dichlorocarbene followed by fluoride-promoted elimination to formcyclopropenes
