Terminal alkyne metathesis has been improved upon addition of quinuclidine as an external ligand to the (tBuO)3WCtBu carbyne complex, giving yield of 80% during hept-1-yne metathesis. Extension of this system to terminal/ disubstituted alkynes co-metathesis affords the expected cross reaction products.
