Application
Ethynyltributylstannane can be used as a reactant to prepare:
- Terminal arylacetylene derivatives by Stille coupling reaction with aryl halides in the presence of palladium catalyst.
- 1,4-bis(tributylstannyl)but-1-en-3-yne by dimerization using a metal complex having bulky ligand catalyst system.
- Isoquinolone derivatives by reacting with benzotriazinones via denitrogenative insertion in the presence of nickel catalyst.
- Enyne key intermediates in the total synthesis of (-)-acutumine and (-)-dechloroacutumine.
