A NOVEL HETEROCYCLIC REARRANGEMENT: CONVERSION OF BENZOYL PYRAZOLINES INTO PHENYLPYRIDAZINONES

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.
