Efficient copper-free Sonogashira coupling of aryl chlorides with palladium on charcoal.

Anna Komáromi1, Zoltán Novák.   

Abstract

Palladium on charcoal serves as an efficient and reusable solid supported catalyst for the Sonogashira coupling of aryl chlorides with terminal acetylenes in the presence of a bulky, electron-rich biphenyl type ligand (XPhos), without copper co-catalyst.
