The reactions of 2-diazo-1,2-diphenylethanone (1) with ketohydrazones (3a–c) in equimolecular ratio yield (diphenylacetyl)hydrazones (4a–c) of the corresponding benzophenones which on further treatment with 1 in equimolecular ratio leads to 1-diphenylacetylazo-1,1,3,3-tetraaryl-2-propanones (5a–c). The product 5a is also obtained in the reaction of 1 with benzophenone hydrazone (3a) in 2 : 1 molecular

The synthesis of a series of 5,6-diarylpyridazinones is described. Some members of this series display an antihypertensive effect in both the spontaneously hypertensive rat (SHR) model and the deoxycorticosteroid (DOCA) model of hypertension. The most potent compounds in the series have halogen substituents on the 5,6-diphenyl rings, a beta-substituted alkyl group at the 2 position of the ring, and acetyl or cyano substituent at the 4 position.
