Base-Free Palladium-Catalyzed Sonogashira Coupling Using Organogold Complexes

Base-Free Palladium-Catalyzed Sonogashira Coupling Using Organogold Complexes

Turn to gold: An effective protocol for base‐free Sonogashira coupling reactions using organogold complexes as nucleophilic partners has been developed. The palladium‐catalyzed methodology offers a general synthesis of aryl–alkynes under operationally simple conditions in good to excellent yields....
