3-Azafluorenes with nitrogen-containing substituents in the C9 position

In the case of the reaction of 9-bromo-4-azafluorene with 2, 5-dimethyl-4-piperidone and p-anisidine it was confirmed that the reactions of this bromide with secondary aliphatic and primary aromatic amines proceed via different mechanisms. Propionyl and phenylcarbamoyl derivatives of 9-bis (β-hydroxy-ethyl) amino-4-azafluorene were synthesized. Spectral data on the pseudoazulenes formed from 9-morpholino-4-aza-fluorene mono- and dimethiodide were obtained. © 1986 Plenum Publishing Corporation.
