Ultrasound-Assisted Synthesis of Functionalized 1,3-Enynes by Palladium-Catalyzed Cross-Coupling Reaction of α-Styrylbutyltelluride with Alkynyltrifluoroborate Salts

Abstract An ultrasound-assisted synthesis of functionalized 1,3-enyne scaffolds is described and illustrated by palladium-catalyzed cross-coupling of potassium alkynyltrifluoroborate salts and α-styrylbutyltellurides. This procedure offers easy access to 1,3-enyne architecture that contains aliphati...

Description
Summary:Abstract An ultrasound-assisted synthesis of functionalized 1,3-enyne scaffolds is described and illustrated by palladium-catalyzed cross-coupling of potassium alkynyltrifluoroborate salts and α-styrylbutyltellurides. This procedure offers easy access to 1,3-enyne architecture that contains aliphatic and aromatic groups in good to excellent yields.
