Sulfuric Acid → (3E)-4-(2,6,6-Trimethyl-1-cyclohexen-1-yl)-3-buten-2-ol

Participants

Reaction Steps

β-Ionol was synthesized from β-ionone as described above for synthesis for aα-ionol with the following modification: 20% sodium hydroxide solution was used to hydrolyze the reaction complex in place of the sulfuric acid solution and the separated organic layer was neutralized by washing with water. α-Ionol thus prepared had the following constants: boiling point, 78° C./0.2 mm; nD25 1.4975; yield 5.9 g. Infrared spectrum and GC retention time was identical to that of a commercially available sample.
