Reliable
reactions for the synthesis of two interesting
anthracenetetrones have been identified and optimized. Both syntheses
start from dihydroxy-9,10-anthraquinones and were selected for
maximized efficiency and minimized work load. Work-up of all
reactions can be achieved without column chromatography, which
facilitates further scale-up. So far, both target compounds are
considerably underexplored despite their promising molecular
structure for use in devices and in organic
synthesis, especially as building blocks for π-conjugated compounds.
The crystal structure of 1,4,5,8-anthracentetrone is reported.
