Methyl carbon shieldings also offer conformational insight in cyclohexanones. In cis-3,5-dimethyl- and 3,3,5-trimethyl-cyclohexanones the equatorial 3-methyl carbon absorbs at ca. 22.3 p.p.m. whereas an equatorial 2-methyl carbon experiences an upfield shift to 14.6 p.p.m. ascribed to a y-interaction between methyl and oxygen. From related compounds these shifts have been estimated as 19.3 and 17.4 p.p.m. respectively. In the former case the upfield shift of 3 p,p.m. is less than the corresponding cyclohexane value on account of the smaller number of syn-axial interactions. In 3-methylcyclohexanone the methyl shielding indicates about 10% axial methyl conformer, corresponding to —AG of ca. 1.3 kcal mol . In cis-2,5-dimethylcyclo-hexanone (67) the observed methyl shieldings of 15.3 and 19.8 p.p.m. are in accord with an equilibrium which contains ca. 80% (67a).
