Reduction of 2,4-di-tert-butylphenol over Raney Ni at 180°, followed by CrO3 oxidation of the mixture and reduction of the resulting ketones gave a mixture of hydrocarbons; this was distilled to give cis-1,3-di-tert-butylcyclohexane (I), b. 223.3-3.5°, nD25 1.4531, and trans-I, b. 229.8-30.0°, nD25 1.4563. Equilibrium between cis- and trans-I was established by heating small samples with Pd-C in sealed tubes with the following results (temperature in °K. and % trans-I, resp.): 492.6°, 2.69; 522.0°, 3.61; 555.0°, 5.09; 580.0°, 6.42; 613.0°, 8.23. From these results a ΔH of 5.9 ± 0.6 kcal./mole and ΔS of 4.9 ± 1.0 e.u. were calculated, the latter value indicating that trans-I was in the boat form.
