The cis-and trans--l.-t-butylcyclohexanols represent a pair of conformationally pure equatorial and axial cyclohexanols with no a-or@-substituents. Thus the rates of reaction and other chemical behavior of the cyclohexanols and their derivatives supply information on the differences to be expected simply from the equatorial or axial disposition of the reactive group on the chair form of the cyclohexane ring. Also, the observed rates are ...
