Zusammenfassung:	NEW MATERIAL:The 1-heptene derivative of formulaI(one of R and R is H and the other is CH3). EXAMPLE:2,6-Dimethyl-1-hepten-3-ol acetate. USE:A sex attractant. Useful as a substance having an activity similar to the sex pheromone of Pseudococcus comstocki. PROCESS:The compound of formulaIcan be prepared in high yield and purity, by reacting the compound of formula III (X is halogen such as Cl, Br, I etc.) with methacrolein of formula IV in the presence of a metal such as Mg in an inert solvent, and acetylating the resultant compound of formula V with an acetylating agent such as acetic anhydride in the absence or solvent of in an inert solvent.
