| Abstract: | Schiff bases in the angular benzindole series that were obtained from 3-formyl[4, 5]- and-[6,7]benzindoles and aromatic amines, on the one hand, and 3-amino[4,5]- and -[6,7]benzindoles and salicylaldehyde, on the other, are described. It is shown that the conformations in each of the [6,7] and [4,5] isomers are identical and are independent of the substituent; this is a consequence of their nonplanar structures.See [1] for communication 18.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 909–915, July, 1979. |
