Diarylpyridazinones could be obtained, in a two-step procedure, from chalcones and diazomethane.The second step involves the rearrangement of a benzoylpyrazoline and proceeds with low yields.The structures have been established by mass and ion-kinetic energy spectrometry.

A series of 3,5-diphenyl-4(1H)-pyridazinones are synthesized by a two-step process, both steps of which are new. In the first step, a phenylglyoxyloyl halide is reacted with a styrylamine in the presence of a base to form a 1-amino-2,4-diphenyl-1-buten-3,

A series of 3,5-diphenyl-4(1H)-pyridazinones and thiones are useful for reducing the vigor of unwanted herbaceous plants. The compounds are effective when applied either preemergence or postemergence to the unwanted plants. The compounds bear 1-alkyl subs
