Photochemical reaction between β-cyclodextrin and p-nitroacetophenone in an inclusion complex in water solution

In aqueous solution and under U.V. irradiation, p-nitroacetophenone oxidizes β-cyclodextrin to give diacetylazoxybenzene. The reaction takes place in the inclusion complex.

Convergent Paired Electrochemical Synthesis of Azoxy and Azo Compounds: An Insight into the Reaction Mechanism

A convergent paired electrochemical method was developed for the synthesis of azoxy and azo compounds starting from the corresponding nitroarenes. We propose a unique mechanism for electrosynthesis of azoxy and azo compounds. We find that both anodic and cathodic reactions are responsible for the synthesis of these compounds. The synthesis of azoxy and azo derivatives have been successfully performed in an undivided cell, using carbon rod electrodes, by constant current electrolysis at room temperature.

Photochemistry of p-Nitroacetophenone in 2-Propanol

Upon irradiation in 2-propanol, p-nitroacetophenone 1 was reduced via the triplet state to p-hydroxyammoacetophenone 5 which was further reduced top-aminoacetophenone 2 and 4,4′-diacetylazobenzene 4. Similar irradiation of 5 also gave 2 and 4, and its oxidation by oxygen gave 4,4′-diacetylazoxybenzene 3. Photolysis of monomeric p-nitrosoacetophenone 6 afforded acetophenone and 3 that were not produced during the irradiation of 1 Possible photoreaction pathways were discussed on the basis of published mechanisms.

NEW TRANSFORMATIONS OF o-SUBSTITUTED AZOXYBENZENES

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.
