Abstract
In this paper are described the syntheses of all positional and geometrical isomers of n-hexyn-1-ols and n-hexen-l-ols. Each of 2-, 3-, 4- and 5-hexyn-l-ol was synthesized from sodium-acetylide in liquid ammonia in higher yield. Then 2-, 3-, 4-trans- and 5-hexen-l-ol were obtained by the reduction of corresponding n-hexyn-l-ol with sodium in liquid ammonia, and 2-, 3- and 4-cis-hexen-l-ol were prepared by the partial hydrogenation at low temperature using palladium-bariumsulfate catalyst. These alcohols were purified through the 3, 5-dinitrobenzoates. The infrared spectra of above compounds were discussed.
