A new class of 6,13-bis(arylamino)triphenodithiazines has been synthesized by condensing chloranil with arylamines followed by the reaction of the resulting 2,5-bis(arylamino)-3,6-dichloro-1,4-benzoquinones with zinc 2-aminobenzenthiolates (4) in the presence of a base in Methyl Cellosolve. On the other hand, the reaction of 2,5-dianilino-3,6-dichloro-1,4-benzoquinone (3a) with 4 in DMF proceeded unexpectedly to give 7,14-dihydro-6,13-triphenodithiazinequinones by eliminating the anilino groups of 3a.
一种新的 6,13-双(芳基氨基)三吩二噻嗪类化合物是通过将氯苯胺与芳基胺缩合,然后将生成的 2,5-双(芳基氨基)-3,6-二氯-1,4-苯醌与 2-氨基苯硫酚锌盐(4)在甲基赛洛溶液中的碱存在下反应合成的。另一方面,2,5-二苯胺基-3,6-二氯-1,4-苯醌(3a)与 4 在 DMF 中的反应出乎意料地进行,通过消除 3a 的苯胺基团,得到 7,14-二氢-6,13-三苯二噻嗪醌。
