Regeneration of Aromatic Carbonyl Compounds from the Corresponding Oximes Using Tetrapyridine Silver(II) Peroxydisulfate in Acetonitrile and Aqueous Media

Abstract

The results of the recovery of both aldehyde and ketone carbonyl functionalities from the oxime derivatives in aromatic carbonyl compounds using tetrapyridine silver(II) peroxydisulfate [Ag(py)₄S₂O₈] as a stable, mild, and efficient oxidizing agent is reported. Yields in excess of 85% were achieved at room temperature in both acetonitrile and aqueous media, making the method versatile and suitable for a wide range of aromatic carbonyl oximes.

Keywords:

• Acetonitrile
• carbonyl
• oxime
• peroxydisulfate ion
• water

ACKNOWLEDGMENT

The investigation has enjoyed the support of the Payam Noor University of Fariman and Mashhad.

Notes

^a Yields refer to the isolated products and 2,4-dinitrophenyl-hydrazine derivatives. Structures were confirmed by IR, ¹H NMR, ¹³C NMR, and mp/bp.
