2,6-Dimethyl-4-m-tolylcyclohex-3-enecarboxylic acid

Abstract

The title compound, C16H20O2, was synthesized to study the hydrogen-bonding interaction of the two enantiomers in the solid state. The racemate is made up of carboxylic acid RS dimers. Intermolecular O—H...O hydrogen bonds produce centrosymmetric R22(8) rings which dimerize the two chiral enantiomers through their carboxyl groups. The chirality of this compound is generated by the presence of the double bond in the cyclohexene ring and a chiral axis due to the meta-methyl substituent on the aromatic ring.
