Abstract
Process for the preparation of propynylcarnols, characterized in that a propyl halide is reacted with a ketone of the general formula r-co-r "by zinc, in which r represents an ethyl group, r" a methyl group or ethyl, and r and r "can be joined to form a cyclopentane with the carbon atom to which they are bound and because the formed zinc compound is decomposed by hydrolysis.
