Abstract

The invention comprises cyclododeca-5 : 9-dienols and their esters with organic acids. These compounds are prepared by reacting a cyclododeca-1 : 5 : 9-triene with an organic acid to obtain an ester and saponifying the latter, the preferred organic acids being formic, acetic and trifluoroacetic acids. In this manner, the trans-trans-trans-triene gives the trans-trans-cyclododecadienol, while the trans-trans-cis-triene gives a mixture of cis-trans- and trans-cis-cyclododecadienols besides the trans-trans-compound. The alcohols may be hydrogenated to give cyclododecanol and the trans-trans-alcohol gives a crystalline phenylurethane. Esters of the dienols with unspecified higher fatty acids or aromatic acids may be prepared by transesterification of the formates.
