実験手順

Acetone under the reaction conditions forms also some diacetone alcohol and mesityl oxide, and these then react with the prenyl chloride to produce the above isomers of prenyl mesityl oxide, also called prenyl-substituted methyl pentenones, in the same manner as acetone reacts with prenyl chloride to produce methyl heptenone. It is also possible that prenyl chloride reacts with the diacetone alcohol in the same manner to give the corresponding hydroxy derivatives that subsequently dehydrate. The presence of such hydroxy ketones is observed in the residues of the methyl heptenone production by the process of U.S. Pat. No. 3,668,255.
