- 中文摘要: Except for substituted acetophenones (p-Y-C/sub 6/ H/sub 4/COCH/sub 3/, Y=H, Br, CH/sub 3/O), simple ketones,.beta.-ketoesters and 1,3-diketones reacted smoothly with a preformed homogeneous mixture of hydrochloric acid and potassium permanganate in acetonitrile to give moderate to good yields of the corresponding .alpha.-chlorocarbonyl compounds. Mixtures of .alpha.-chloro- and .alpha.,.alpha.- dichlorocarbonyl compounds were obtained for substituted acetophenones. Brominations proceeded similarly with higher yields when the hydrochloric acid was replaced with hydrobromic acid.
