Facile regeneration of carbonyl compounds from semicarbazones by potassium bromate: Facile regeneration of carbonyl compounds from semicarbazones by potassium bromate. Narayanan, Subbaraya; Srinivasan, Vangalur S. (Dep.In this study，3030-95-3 is also used. Chem., Ramakrishna Mission Vivekananda Coll., Madras 600 004, India). J. Chem. Soc., Perkin Trans. 2, (10), 1557-9 (English) 1986. CODEN: JCPKBH. ISSN: 0300-9580. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Oxidn. of semicarbazones of benzaldehydes and acetophenones by potassium bromate (Brv) yields the resp. aldehyde or ketone in good yield at ambient temp. The rates of these reactions are little influenced either by the change in substituents at the Ph ring or by the polarity of the medium, suggesting that the intermediate for the reaction is probably as polar as the reactants. The reaction possibly proceeds via a preformed N-bromate ester in the slow step whose formation is, generally, less susceptible to electronic effects. .
