The synthesis of derivatives of [14]annuleno[14]annulene, [14]annuleno[16]annulene, and [14]annuleno[18]annulene, bicyclic compounds consisting of two ortho fused macrocyclic conjugated .pi. systems
The synthesis of derivatives of [14]annuleno[14]annulene, [14]annuleno[16]annulene, and [14]annuleno[18]annulene, bicyclic compounds consisting of two ortho fused macrocyclic conjugated .pi. systems
A bisdehydro[14]annuleno[c]furan and a tetrakisdehydro[14]annuleno[14]annulene have been synthesized; their properties and effects of annelation on annulene rings are discussed on the basis of 1H NMR and electronic spectra. Attempts to synthesize the related [14]annuleno[16]annuleno[14]annulene are also described.
