Study on the oxidation of bis (α-methylene carbonyl) compounds

Abstract

The oxidation of bis(α-methylene carbonyl) compounds was studied by using (i) DMSO and HBr or (ii) DMSO, HCl and KI as oxidizing agents. It is found that these reactions using DMSO with a suitable amount of HBr or HCl with KI result in higher yield and higher purity of bis (1,2-dicarbonyl) compounds as compared with the commonly used oxidizing agents, such as SeO2. The yield and the melting points of these products as well as the elemental analysis, mass spectroscopy and NMR spectroscopy are reported in this paper.

Key words: OXIDATION, DMSO, CARBONYL COMPOUNDS, OXIDANT
