5-Hexen-1-ol Usage And Synthesis

Chemical Properties

Clear, colorless liquid with a green aroma.

Uses

5-Hexen-1-ol is used in cyclization to a tetrahydropyran by phenylselenoetherification. It is also used as a building block in synthetic chemistry. Further, it is used to prepare 6-bromo-hex-1-ene by reaction with phosphorus tribromide.

Preparation

5-hexen-1-ol may be prepared from 2-(chloromethyl)tetrahydropyran according to the literature procedure for the preparation of 4-penten-1-ol (Brooks, L. A.; Snyder, H. R. Org. Synth. Coll. Vol. III 1955, 698).

Application

5-Hexen-1-ol is used as a food flavouring agent and as a raw material in organic synthesis for cyclisation to other compounds such as tetrahydropyran via phenylselenide etherification.

Aroma threshold values

Medium strength odor; recommend smelling in a 10.00% solution or less
