TLDR
In this article, 5-Bromo-and 5-nitro-isatin condense with substituted anilines to isatin-3-(phenyl)-imines.
Abstract: 
5-Brom- und 5-Nitro-isatin kondensieren mit substituierten Anilinen zu Isatin-3-(phenyl)-iminen. 5-Brom-isatin-3-(phenyl und naphthyl)-imin werden auch durch Bromieren von Isatin-3-(phenyl und naphthyl)-imin erhalten. Bei Einsatz von o-Phenylendiamin erfolgt Ringschlus zu 5-Brom-bzw. 5-Nitro-6,11-diaza-5H-benzo[b]carbazol, wobei als Zwischenprodukt wahrscheinlich die entsprechenden Isatin-3-(o-amino-phenyl)-imine auftreten. Substituted Isatin Phenylimines. 5-Bromo- and 5-nitro-isatin condense with substituted anilines to isatin-3-(phenyl)-imines. 5-Bromo-isatin-3-(phenyl- and naphthyl)-imine are obtained also by bromination of isatin-3-(phenyl- and naphthyl)-imine. The reaction with o-phenylenediamine gives ring closed 5-bromo-and 5-nitro-6,11-diaza-5H-benzo-[b]-carbazoles. The isatin-3-(o-aminophenyl)-imines may act as intermediates in this reaction.
