Abstract

Abstract: Examination of the conformational equilibria of I-phenyl-3, 3, t-5- trimethylcyclohexane and l-phenyl-1, 3, 3-trimethylcyclohexane by low-temperature" CNMR spectroscopy indicates the 1, 3-diaxial interaction of phenyl and methyl to amount to 3.4 f 0.1 kcal/mol. The gauche interaction of the methyl substituents in trans-l, 2-dimethylcyclohexane is measured as 0.74 kcal/mol through determination, by the same technique, of the ...
