Aliphatische Azoverbindungen, XIII: cis‐ und trans‐1‐Azonorbornan

Abstract: Die Isomerisierungsgeschwindigkeit von cis-in iruns-1-Azonorbornan (1) folgt bei 96.6"C linear dem Polaritatsparameter E : ' in verschiedenen aprotischen Losungsmitteln. Die geringe Steigung -0.034 dieser Korrelation deutet auf einen theoretisch vorgeschlagenen einfachen Inversionsmechanismus. In protischen Losungsrnitteln verlauft die Isomerisierung vie1 schneller, wofiir ein durch H-Brijcken begiinstigter Rotationsmechanismus moglich gehalten wird. Reaktionsenthalpie und Aktivierungsparameter der cis-rrans-I… Show more
