c acid derivatives (I)—(III) has been studied and the free energy of activation of internal rotation about the aryl–cyclohexenone bond in each determined from the coalescence temperature. The 1-naphthyl derivative (I) possesses an appreciable energy barrier (ca. 22 kcal mol–1) which is lowered considerably by the introduction of a methoxy-group adjacent to the pivot bond [as in (II)]. Some plausible
