Dibenzacridines have been synthesized in good yields by thermal cyclization (140-180 deg C) of N-aryl-4-chloro-1-aza-1,3-butadiene derivatives followed by dehydrogenation.

We reported herein CuI/DMEDA catalyzed N,N-diarylation reaction of amides with various di(o-bromoaryl)methanes to produce diverse 9,10-dihydroacridine derivatives. The resulting 9,10-dihydroacridine derivatives were oxidized selectively under mild conditions to afford acridine, acridinone, and acridinium derivatives. The copper-catalyzed N,N-diarylation reaction coupled with oxidative aromatization reaction enabled the facile construction of nitrogen atom-embedded tetracenes and pentacenes of different ortho-fused patterns. The luminescence properties, especially the effect of fusion pattern on fluorescence emission of acquired N-polycenes, were also demonstrated.

Selbin, J.,Gutierrez, M. A.
, p. 95 - 104 (2007/10/02)
The first cyclometallated compounds of some 2,6-diarylpyridines (2) and the related ligand, 5,6,8,9-tetrahydrodibenzacridine (3) were prepared and characterized as acetato-bridged palladium(II) dimers: 2.Inseparable isomers (syn,trans
