                                    This paper presents an efficient methodology for the preparation of dibenzoxepino[4,5-d]pyrazoles using a novel intramolecular palladium catalyzed diaryl ether formation. The effect of different chelating ligand systems, along with the unusual coupling reaction of phenoxides with aryl iodides and non-activated aryl moieties are also reported.
