Abstract

Triarylsulfonium, alkyl- and fluoroalkyl(diaryl)sulfonium, and aryl(dialkyl)sulfonium triflates are successfully used as cross-coupling participants in the Sonogashira reaction. Terminal alkynes reacted mildly with arylsulfonium salts at room temperature under Pd- and Cu-cocatalysis to give the corresponding arylalkynes in very good yield.
