Abstract
AbstractTerminal alkyne metathesis has been improved by addition of quinuclidine as an external ligand to the (t‐BuO)3WCBu‐t carbyne complex, giving a yield of 80 % during hept‐1‐yne metathesis. Extension of this system to the co‐metathesis of terminal and disubstituted alkynes affords the expected cross‐reaction products.
