Graphical Abstract
  • protocol has a broad scope for the bromination of various substituted and unsubstituted aminoanthracene-9,10-diones. Keywords: aminoanthracene-9,10-dione; benzanthrone; KBr; nonanebis(peroxoic acid); oxidative bromination; Introduction The brominated aminoanthracene-9,10-dione derivatives and
  • benzanthrone are widely used as intermediates for pharmaceuticals [1][2][3], for medicinal applications [4], as dyes [5][6][7][8][9] and in Hg2+ ion sensors [10]. Although these bromo derivatives have a wide range of applications, it is difficult to carry out their bromination as the two carbonyl groups of

  • stable enol 4, which is converted by dehydrogenation into the benzanthrone derivative 7. Under acidic conditions 4 isomerises to the spiro compound 11 and the bicyclo[4.3.1]decane derivative 12. Furthermore, the formation of 7 and the hydrogenated compound 13 is observed. A mechanism for the formation of
  • -emitting diodes, OLEDs) or light-harvesting properties (e.g. organic solar cells) are receiving more and more attention [1]. In this respect benzanthrone (1), with its luminescent and photosensitizing properties, is an interesting candidate for the construction of these systems. Recently, aminobenzanthrone
