Ultrasound-assisted synthesis of aromatic 1,2-diketones from oximinoketones under neutral conditions in aqueous media

We report a convenient, neutral, and facile methodology for the synthesis of aromatic 1,2-diketones from the corresponding oximinoketones in the presence of I2/SDS/water system under ultrasound-assisted conditions. Furthermore, a series of compounds were synthesized and characterized by melting point, IR, NMR, MS, and elemental analysis. Utilization of easy reaction conditions, very high to excellent yields, and short reaction times makes this manipulation potentially very useful.
