Palladium-catalysed direct polyheteroarylation of di- or tribromobenzene derivatives: a one step synthesis of conjugated poly(hetero)aromatics

Abstract

The palladium catalysed polyheteroarylation of benzene, biphenyl, fluorene, naphthalene or antracene derivatives via C–H bond functionalisation allows the synthesis of a wide variety of functionalised conjugated poly(hetero)aromatics in only one step. This simple method provides a powerful tool to material chemists allowing to tune easily the physical properties of materials.
