Facile synthesis of unsymmetrical and π-extended furan-diketopyrrolopyrrole derivatives through C–H direct (hetero)arylation using a heterogeneous catalyst system

Abstract

A mono functionalization of bis-furandiketopyrrolopyrrole (DPPFu₂) via direct (hetero)arylation has been developed. This method allows for rapid access to a new family of narrow band-gap, π-extended DPP derivatives via consecutive C–H bond activation between mono-arylated DPP and aryl bromides with heterogeneous catalysts in a simple fashion.
