Besonderheiten bei der Ozonolyse substituierter Cyclopentene

Abstract: Saarbrücken, Fachrichtung 11.2 Organische Chemie der Universität des Saarlandes Eingegangen am 17. Januar 1995 Details on Ozonolyses of Substituted Cyclopentenes In ihrer Studie über "Intramolekulare Konkurrenzreaktionen bei der Ozonolyse substituierter Cyclopentene" gingen Criegee und Mitarbeiter [1] aufgrund früherer Erfahrungen [2] davon aus, daß Cyclopentene 1 (R 1 , R 2 = H) mit 2 H-Atomen an der Doppelbindung unter den üblichen Alkenozonolysebedingungen in Lösung nicht mehr zur Bildung monomerer Ozonide … Show more

“…The former situation could have occurred with the rigid cyclic alkene 36, and represents an oxygenative ring enlargement of a strained five-membered ring to a less strained six-membered ring. Our earlier communication on cyclopentene ring ozonolyses [56] already challenged the Criegee mechanism. In the case of electron exchange between unsaturated hydrocarbons and O 3 , it is not necessary that the initial SET be exergonic; exergonic SET is required only when stationary concentrations of free cation radicals are needed for spectral observations.…”
