Substituted 6-ethoxyanilino-5H-benzo[a]phenothiazin-5-ones (3a-f) were synthesized by the cyclocondensation of 2-chloro-3-ethoxyanilino-1,4-naphthoquinones with zinc mercaptides of 2-aminothiophenol in pyridine. The nmr, ir and mass spectral data are presented and discussed.

A number of substituted 6,13-dihalogenotriphenodioxazines have been synthesised (a) by condensing halogeno-p-benzoquinones with arylamines followed by cyclisation of the resulting bisarylamino-quinones with benzoyl chloride in nitrobenzene and (b) by condensing halogeno-p-benzoquinones with o-aminophenols in the presence of anhydrous sodium acetate in an alcoholic medium. A few triphenodithiazines
