title: Unusual aryl migration in a mesomeric betaine in the solid and liquid state: mechanistic insights into the SNAr reaction.
abstract: An intramolecular S(N)Ar mechanism has been identified in the unexpected aryl migration observed in a mesomeric betaine. The process changes drastically the optical and spectroscopic properties and should be a valuable model for related heteroaromatic systems.
