Racemic 4-(4-tert-butylphenyl)-2,6-dimethylcyclohex-3-enecarboxylic acid

S. Xie, C. R. O'Hearn and P. D. Robinson

Abstract: The chirality of the title compound, C₁₉H₂₆O₂, is solely generated by the presence of the double bond in the cyclohexene ring. This compound was synthesized to study the interaction of the two enantiomers in the solid state. The resultant racemate is made up of carboxylic acid RS dimers. Intermolecular O-HO hydrogen bonds produce centrosymmetric R₂²(8) rings which dimerize the two chiral enantiomers through their carboxyl groups.
