Under the influence of equimolar amounts of bases, o-propionylazoxybenzenes undergo previously unknown transformations to difficult-to-obtain cinnolinones, bisindoxyls, and indolinones.The rations of the resulting transformation products depend on the substituent in the para position with respect to the propionyl group.Possible pathways for the transformations of monopropionylazoxybenzenes are discussed.

2,2'-Dipropionylazoxybenzenes undergo rearrangement to the corresponding 3-benzoisoxazoles in the case of base catalysis; this transformation is realized only in the case of ortho,ortho' orientation of the propionyl groups in the substrate molecule and with the participation of the solvent as a reagent.A mechanism for the rearrangement that assumed the participation of one of the propionyl groups in intramolecular reduction of the azoxy group to an azo group is proposed.
