Description and Uses

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.
