Terminal alkyne metathesis has been improved by addition of quinuclidine as an external ligand to the ( t‐ BuO) 3 WCBu‐ 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.
