Abstract

Acetyl-and benzoylacetones were aroylated not only with methyl benzoate but also with other appropriate aromatic esters to form triketones Ia-f. Similarly, 2-acetylcyclohexanone, 2- acetylcyclopentanone, and o-hydroxyacetophenone were aroylated with the appropriate esters to give triketones IIa-b, 111 and IV respectively. The results are summarized in Tables I and 11.
