Acyclic terpenes and alicyclic alcohols were isomerized and dehydrogenated with catalyst systems composed of copper and zinc over a temperature range from 160 to 262°C under a reduced pressure.<BR>Geranial, neral, citronellal, dihydrocitronellal, myrcene, and homoperillyl alcohol were obtained by the isomerization and dehydrogenation of geraniol [1], nerol [2], citronellol [3], dihydrocitronellol [4], 2- (10) -pinene [5], and nopol [6], respectively.<BR>In addition, dehydrogenation of alcohols, such as cyclopentanol [7], cyclohexanol [8], 2-methylcyclohexanol [9], and cyclooctanol [10] gave corresponding alicyclic oxo-compound in almost quantitative yields.<BR>The most suitable conditions for the reactions mentioned above were proposed in the light of the experimental results.
