Unusual (but precedented) equilibrium between 1,4- and 1,6-Di(2- hydroxyethyl)cyclooctatetraene
摘要:
At equilibrium, the apparently sterically more congested 1,6-isomer of di(2-hydroxyethyl)cyclooctatetraene predominates over the 1,4-isomer in aqueous solution. Such behavior has previously been observed for the isomers of di-tert-butylcyclooctatetraene in organic solvent 1 and is likely due to intramolecular van der Waals attraction.
