Dibenzofuran and its derivatives are ubiquitous and important medicinal and natural products. Many contain electron-donating substituents. Herein, we report a Pd-catalysed C−H functionalisation protocol that works with electron-rich arenes. We use tetrabutylammonium acetate (NBu4OAc), which we suspect can act as base and ligand, rendering this protocol a simple and efficient route to dibenzofurans
