Conformational analysis of 5-t-butylcyclohexa-1,3-diene
Abstract
Analysis of variable temperature circular dichroism spectra of (+)-(5R)-t-butylcyclohexa-1,3-diene gave a conformational energy of 1·7 kJ/mol, indicating that where 1,3-diaxial interactions are minimised, the equatorial configuration is only slightly favoured over the axial.
