Abstract

The ^13^C NMR spectra of a series of 4‐t‐butylcyclohexane‐O‐methyl oximes and N,N‐dimethylhydrazones containing α‐methyl substituents have been measured. The effects of α‐methyl substitution (syn‐axial, anti‐axial and anti‐equatorial) on the carbons α, β and γ to the substitution site are similar to those previously found in cyclohexanones. Use has been made of these substituent parameters to determine the conformational equilibria of the mobile 2‐methylcyclohexanone derivatives.
