Abstract

original image

Eine Klasse definierter reversibler σ-Dimerisierungen von 9,10-Dialkoxyanthracen-Radikalkationen wird vorgestellt. Gelbe Kristalle, die das σ-dimerisierte Dikation enthalten, ergeben violette Lösungen mit monomeren Radikalkationen (siehe Schema). Identität und Stabilität der Radikalkationen wurden bestätigt, wodurch der Nachweis für reversible σ-Dimerisierungen beständiger Radikalkationen von aromatischen Systemen erbracht wurde.
