and Pd-catalyzed, silicon-assisted intramolecular cross-coupling has been developed to provide an effective and powerfulmethod for construction of medium-sized rings with an internal 1,3-cis-cis diene unit. Allylic alcohols bearing a Z-iodoalkenyl tether can be silylated with chlorodimethylvinylsilane and subjected to Mo-catalyzed ring-closing metathesis to form unsaturated siloxanes. Activation of
