Heptatrienes, autoxidation

The autoxidation of 4-undecanone in ah at 130 °C leads to the formation of hydroperoxides, which decompose at 120-160 °C via different radical pathways to give CO, CO2, and H2 by parallel pseudomonomolecular processes.304 An extremely sterically crowded heptatriene (141) is reported to undergo autoxidation at 25 °C in cyclohexane. The isolated products were rationalized by the dissociation of (141) to the tropyl radical (142) or fluorenyl radical (143) and subsequent attack by molecular oxygen (Scheme 22).305...
