Condensed Ring Systems, XVI1). Synthesis, Crystal and Molecular Structure of a 1,4-Bridged Dewar-Benzene of the [6.2.2]Propellane Series with Conformational EnantiomerismStarting from 3,4:5,6-dibenzo-10,13-dithia[6.3.3]propella-3,5-diene (1) racemic 3,4:5,6-dibenzo-[6.2.2]propella-3,5,9,11-tetraene (7) is prepared. Its constitution is established by X-ray structure analysis. An enantiomeric enrichment of 7 has been achieved by chromatography on triacetyl cellulose; its halflife at 20°C is about 100 h.
Notes:
Ausgehend von 3,4:5,6-Dibenzo-10,13-dithia[6.3.3]propella-3,5-dien (1) wird das racemische 3,4:5,6-Dibenzo[6.2.2]propella-3,5,9,11-tetraen (7) hergestellt. Seine Konstitution wird röntgenstrukturanalytisch bewiesen. Durch Chromatographie an Triacetylcellulose konnte eine Anreicherung der Enantiomeren von 7 erreicht werden, deren Halbwertszeit bei 20°C ca. 100 h beträgt.
