Zusammenfassung

4-Brom-, 5-Brom- und 4,6-Dibrom-benzimidazol wurden synthetisiert und ihre UV-Spektren aufgenommen. Die Darstellung des 4,6-Dibrom-benzimidazols gelang durch Erhitzen von 2-Amino-4,6-dibromacetanilid oder 4,6-Dibrom-N,N′-diacetyl-o-phenylendiamin auf höhere Temperaturen. Die Bromierung von 2-Nitroanilin und 2-Methyl-5-brombenzimidazol wurde näher untersucht.

Abstract

4-Bromo-, 5-bromo- and 4,6-dibromobenzimidazole have been prepared and their ultraviolet absorption spectra recorded. The synthesis of the latter was achieved by heating of either 2 amino-4,6-dibromoacetanilide or 4,6-dibromo-N,N′-diacetyl-o-phenylenediamine to higher temperatures. The bromination of 2-nitroaniline and 2-methyl-5-bromobenzimidazole has been investigated.
