Abstract

Acetylation of lower 1,3-cycloalkenediones with ketene takes place exclusively at oxygen in contrast to acyclic β-diketones. Thus, 1,3-cyclopentanedione (<i>I</i>), 1,3-cyclohexanedione (<i>II</i>) and 5,5-dimethyl-1,3-cyclohexanedione (<i>III</i>) afforded the corresponding 3-acetoxy-2-cycloalken-1-ones <i>VI - VIII</i> in quantitative yields. 1,3-Cycloheptanedione (<i>IV</i>) and 1,3-cyclooctanedione (<i>V</i>) differed considerably from the preceding diketones by low reactivities.
