摘要： Mono-Oxidation of alpha-aroyl ketene dithioacetals 1 by equimolar hydrogen peroxide in acetic acid at room temperature afforded both Z- and E-configurated mono-sulfoxide derivatives 2 and 3 with Z-isomers 2 as the predominant products. Acid catalysed isomeric equilibration of 2 or 3 leads to a mixture in which the Z-isomer predominates.
