Hydrogenolysis of 2,6-dimethyl-3-heptyne-2,6-diol

Abstract

Catalytic hydrogenation of 2,6-dimethyl-3-heptyne-2,6-diol under ordinary pressure and temperature resulted hydrogenolysis products, the amount of which was about half mole of used diol. By means of IR, NMR and others, the hydrogenolysis product was identified with 2,6-dimethyl-2-heptanol which synthesized from methylheptanone. It was infered from the NMR spectrogram of the hydrogenolysis product of 2,6-dimethyl-3-heptyne-2,6-diol-d6 that elimination of OH group takes place in similar ratio on the OH group of 2 and 6 position.
