Abstract

original image

Formation of ion pair by solvation is invoked to explain the 1H-NMR spectral result obtained for (1) and the analogous cyclonatetraene derivative. Thus (1) is capable of not only intramolecular exchange [(1′)(1)] but also intermolecular exchange of substituents (e.g in HMPT as doner solvent[DOUBLE BOND]Do).
