Although the hydrochloride of c-4-t-butyl-l-phenyl-c-l-(N-piperidyl)cyclohexane crystallizes in the conformation with axial-t-butyl, it exists as an almost equimolar mixture of the two chair conformers in CD-Cl\_ solution. -The nosition of eauilibrium allows one to calculate AG:-Bu as -4.9 kcal/mol.
Esppsure of aqueous glassy solutions of f-butyl alcohol to 6oCo vlays at 77Β°K gave ESR spectra characteristic of h!e& and H2CC(hfe)20H radicals. The results for the former were unusual in fh?t, for very dilute aqueous solutions and for solutions of 0.4 mole fraction through to the pure alcohol, all
