- W1973075786 abstract "Wir berichten über die Darstellungen der mono- und disubstituierten Bicyclo[4.2.2]decatetraene 12 ⇌ 13, 14 ⇌ 15, 16, 17 ⇌ 18, 24 bzw. 19, 20. Die in diesen Molekülen mögliche Diels-Alder/Retro-Diels-Alder-Reaktion führt bei 12 ⇌ 13, 14 ⇌ 15, 17 ⇌ 18 zu einem nachweisbaren Gleichgewichtsgemisch zwischen zwei Valenzisomeren. Die Halbwertszeiten der Verbindungen 13, 18 und 24 liegen bei 35°C zwischen ca. 13 bis 24 Minuten. — Wir informieren ferner über einige Versuche zum Nachweis eines Didehydrobicyclo[4.2.2]decatetraens 37 oder 38. Syntheses and Some Properties of Mono- and Disubstituted Bicyclo[4.2.2]decatetraenes We report the syntheses of the mono- and disubstituted bicyclo[4.2.2]decatetraenes 12 ⇌ 13, 14 ⇌ 15, 16, 17 ⇌ 18, 24 and 19, 20, respectively. The Diels-Alder/retro-Diels-Alder reaction possible in these molecules gives rise to a detectable equilibrium mixture between two valence isomers in the case of 12 ⇌ 13, 14 ⇌ 15 and 17 ⇌ 18. The half-lives of the molecules 13, 18, and 24 at 35°C are of the order of 13 to 24 minutes. — We also describe some experiments designed to detect a didehydrobicyclo[4.2.2]decatetraene 37 or 38." @default.
