Palladium-catalyzed intramolecular arylation of 2-benzyl-5-(2-bromophenyl)-4- phenylpyridazin-3 (2H)-one yielded hitherto unknown 2-benzyldibenzo [f, h] phthalazin-1 (2H)-one. The synthesis of this new tetracyclic pyridazinone from 2-benzyl-5-(2- aminophenyl)-4-phenylpyridazin-3 (2H)-one via a Pschorr type reaction was also investigated. Similarly, the construction of 2-methyldibenzo [f, h] cinnolin-3 (2H)-one from ...
