A wide range of organosilicon compounds couples with enol and aryl triflates in the presence of Pd catalyst and fluoride ion

Under the influence of tetrakis(triphenylphosphine)palladium and tetrabutylammonium fluoride, the title reaction took place with alkenyl, alkynyl, aryl, and alkylsilanes to give the corresponding coupled products in good yields with high chemoselectivity and stereospecificity.
