ortho‐Aryl phenols, synthesized via protecting group free Suzuki–Miyaura coupling of ortho‐halophenols and arene boronic acids, undergo a cyclization to dibenzofurans via oxidative C–H activation. The reaction proceeds under microwave irradiation in short reaction times using catalytic amounts of Pd(OAc)2 without additional ligands.
