摘要：A compound of formula <IMAGE> is prepared by a./treating/Z/-3,7-dimethyl-2,6-octadien-1-ol of the formula /II/ <IMAGE> with a propionating agent, reacting the propanoate thus obtained with a tert.butyl hypohalide, preferably hypochlorite in an aprotic, moderately polar solvent, in the presence of an acidic adsorbent, preferably Kieselgel, reducing the halo compound of the general formula /III/ thus obtained, <IMAGE> wherein R stands for propionyl and Hal represents halogen, with a moderately reactive metal hydride in a polar solvent; or b./reacting/Z/-3,7-dimethyl-2,6-octadien-1-ol of the formula /II/ with a tert-butyl hypohalide, preferably in hypochlorite in a moderately polar solvent, in the presence of an acidic adsorbent, treating the halo compound of the general formula /III/ thus obtained, wherein R represents hydrogen and Hal is halogen,with a reducing agent, preferably lithium aluminum hydride, reacting the /Z/-3,7- dimethyl-2,7 -octadien-1-ol thus obtained with a propionating agent, preferably propanoic chloride, and separating the compound of the formula /I/ thus obtained from in the reaction mixture. Transfer for destroying male San Jose Scale are baited with the compounds of formula I.
