How it is made

Preparation by the reaction of butyne-1 with ethylene oxide and subsequent selective reduction to the cis isomer.

Extracted from various essential oils and purified by reacting it to the corresponding phthalate or allophanate.

A stereospecific synthesis for cis-3-hexen-1-ol starts with the ethylation of sodium acetylide to 1-butyne, which is reacted with ethylene oxide to give 3-hexyn-1-ol. Selective hydrogenation of the triple bond in the presence of palladium catalysts yields cis-3-hexen-1-ol.
