Bridged Tetraphenylene Systems, II.-On the Structure of 4,11-Dihydrodicyclopenta[def, pqr]-tetraphenylene and Its Dilithium DerivativeIt follows from the 1 H-NMR data of the doubly methano-bridged tetraphenylene 1that this compound has a nonplanar structure. This also holds for the 4,11-dilithium derivatives, 3which reacts with iodine to give undefined polymeric products.
Notes:
Aus den 1H-NMR-Daten des zweifach Methano-verbrückten Tetraphenylens 1 folgt, daß diese Verbindung einen nichtplanaren Bau besitzen muß. Gleiches gilt für das 4,11-Dilithium-Derivat 3, das mit lod zu undefinierten polymeren Produkten reagiert.
