摘要：

The diastereotopic methyl signals detected at low temperatures or high concentrations of an azulenylazulenium salt containing prochiral centers are consistent only with a model involving monomers in rapid equilibration with dimers in the staggered ("brickwork") arrangement and not in the "card-stacked" arrangement.
