A sequential ring-closingmetathesis/silicon-assisted cross-coupling sequence has been developed. Alkenyldimethylsilyl ethers of omega-unsaturated alcohols undergo facile ring closure with Schrock's catalyst to afford five-, six-, and seven-membered cycloalkenylsiloxanes bearing substituents on both alkenyl carbons. These siloxanes were highly effective coupling partners with various aryl and alkenyl
