title: Efficient and Z-selective cross-metathesis of conjugated enynes.
abstract: [reaction: see text] The generation of a conjugated alkynyl alkylidene has been achieved using an allyl ether moiety as an intramolecular catalyst delivery vehicle. The reaction of this intermediate with alkenes and alkynes yields conjugated enynes with Z-selectivity.
