A palladium‐catalyzed intramolecular directarylationreaction was developed and two efficient one‐pot sequentialdirectarylation/Suzuki–Miyauracoupling and intra/intermolecular directarylation reations were also realized. The method provides a simple and straightforward procedure for the synthesis and further functionalization of dibenzophosphole oxides from easily accessible ortho‐halodiarylphosphine
