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- ...
