The synthesis of a branched benzoxazinophenothiazine heterocycle is described. The parent compound benzo [a]]1,4]-benzoxazino [3,2-c] phenothiazine (), was obtained from 2,3-dichloro-1,4-naphthoquinone (), 2-aminophenol and 2-amino-thiophenol. Monoaza-, diaza- and triaza- analogues of this novel heterocycle were also synthesized. The parent compounds, 16-oxa-15-thia-4,5,10-triazabenzo [ h ] pentaphene
描述了支链苯并恶嗪吩噻嗪杂环的合成。母体化合物苯并[a]] 1,4]-苯并恶嗪[3,2-c]吩噻嗪()由2,3-二氯-1,4-萘醌(),2-氨基苯酚和2-氨基-硫酚。还合成了该新型杂环的单氮杂,二氮杂和三氮杂类似物。母体化合物16-oxa-15-thia-4,5,10-三氮杂苯并[h]五苯酮()和16-oxa-15-thia-4,5,10,14-四氮杂并苯并[h]五苯酮(,R还合成了= H)以及4-氨基-16-氧杂-15-硫杂-4、5,10,12,14-五氮杂苯并[h]五苯酮(24)。它们是适合用作颜料的深色高熔点固体。Na 2 S 2 O 4易于还原 并且还原的化合物被大气中的氧气迅速氧化为醌型,表明它们也可以用作还原染料。
