Preparation of dien-1-ols, 9-hydroxydodec-10-enyl 1-tert-butyl ether and use thereof as an intermediate for synthesizing 8,10- dodecadienol

摘要

Dien-1-ols of the general formula I ##STR1## where the radicals R.sup. 1 to R.sup.7 are identical to or different from one another and each is hydrogen or straight-chain or branched alkyl or 1-12 carbon atoms and n is 1-14, are prepared by dehydrating a hydroxylalkenyl tert-butyl ether of the formula II ##STR2## in the presence of an acidic catalyst at elevated tempertures and essentially at the same time splitting off the tert-butyl protective group, as is 9-hydroxydodec-10- enyl 1-tert-butyl ether which is useful as an intermediate for synthesizing 8,10- dodecadienol.
