    Description / Table of Contents: Aliphatic Azo Compounds, VII. The Thermolysis of 9-Azo-cis- and 9-Azo-trans-decalinThe title compounds decompose between 180 and 200°C with identical activation parameters at almost the same rate. It is therefore assumed, that the transition states of these thermolysis reactions have still tetrahedral geometry at the developing radical centers at C-9. The product yields are the same from both azo compounds. This confirms the assumption made previously in the literature that the 9-decalyl radicals initially generated undergo a fast conformational change.
    Notes: Die Thermolyse der Titelverbindungen erfolgt zwischen 180 und 200°C mit gleicher Aktivierungs-enthalpie und -entropie und fast gleicher Reaktionsgeschwindigkeit. Es wird daher angenommen, daß die Übergangszustände der beiden Thermolysereaktionen am entstehenden Radikalzentrum noch tetraedische Geometrie besitzen. Die identische Produktverteilung der beiden Thermolysereaktionen bestätigt die bereits früher in der Literatur angenommene schnelle konformative Umwandlung der primär entstehenden Radikale.
