2′-, 3′-, and 4′-(Piperonyloxy)-2-acetoxyacetophenones (V) have been synthesized by the bromination arid subsequent treatment with sodium acetate of the respective (piperonyloxy) acetophenones (III) which in turn were prepared by the reaction of piperonyl chloride with 2′-, 3′-, and 4′-hydroxyacetophenones, respectively, in the presence of alkali.
Alkaline hydrolysis of 2′-, and 4′-(piperonyloxy)-2-acetoxyacetophenones gave the corresponding benzoic acids (VII), while the meta derivative (V) was converted into the hydroxy-ketone (VI) on treatment with boiling water.
