Silane 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.

Potassium triethylsilanolate; Potassium triethylsiloxide; Triethylsilanol, potassium salt
  • Soluble: methylene chloride, THF
  • Catalyst for the cross-coupling of aryl and vinylsilanes
  • Greater solubility and reactivity than KOSiMe3
  • Used as a nucleophiles in the enantioselective formation of allyl alcohols from allyl carbonates
  • Employed in an inexpensive vinylation of aryl bromides
