This book reported the literature survey of the chemistry of dibenzobarallene. The activity of dibenzobarallene and their synthetic importance were investigated. Syntheses, reactions and the biological importance of dibenzobarallene were also investigated. Furthermore, the obtained results were discussed, 51 novel compounds and some related analogues were synthesized, the synthetic mechanisms were investigated and compounds were established by elemental analyses and spectral data. Such novel compounds were prepared in this book based on dibenzobarallene namely; thiocarbamoyl,...
