4-tert-Butylcyclohexanol

Synthesis

Phenol and isobutylene carry out tert-butylation reaction in the presence of aluminum trichloride, and catalytic hydrogenation with Rays Nickel W7, two kinds of geometric structures can be obtained, in which the trans structure accounts for more than 70%.

Chemical Properties

white powder or granules

Occurrence

Has apparently not been reported to occur in nature.

Uses

4-tert-Butylcyclohexanol (mixture of cis and trans) can be used as a reactant to synthesize tris(4,4′-di-tert-butyl-2,2′-bipyridine)(trans-4-tert-butylcyclohexanolato)deca-μ-oxido-heptaoxidoheptavanadium oxide cluster complex by reacting with [V₈O₂₀(C₁₈H₂₄N₂)₄]. It can also be used as a reactant in competitive Oppenauer oxidation experiments in the presence of zeolite BEA as a stereoselective catalyst. Only cis-isomer is selectively converted to the corresponding ketone, whereas trans-isomer remains unchanged.

Preparation

From 4-terf-butylphenol by hydrogenation(Arctander, 1969).
