Oxidative cleavage of oximes with peroxymonosulfate ion

We continue to be interested in developing a general, powerful and environmentally benign oxidation protocol capable of oxidizing a large variety of functional groups either with oxone(R) or oxone(R) in aqueous acetone. Peroxymonosulfate ion, HSO5-, which is usually used as a oxone(R) (2KHSO(5), KHSO4, K2SO4) is a very cheap, safe and versatile oxidant used for the transformation of a wide range of functional groups(1). In this regard, we have recently reported a mild oxidation of nitriles to amides(2). In this communication we are pleased to describe some of our results for the regeneration of carbonyl compounds from stable and readily available aldoximes and ketoximes in good yields.
