  • 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.

    Silicon-Based Formation of Carbon-Carbon Bonds – Larson

    Hatanaka and Hiyama first reported the palladium-catalyzed, fluoride-promoted reaction of aryl, alkenyl, allyl, and ethynyltrimethylsilanes with aryl, vinil and allyl halides to form the respective cross-coupled products
