The synthesis and characterization of new complex monoaza and pentaaza angular phenothiazine derivatives is reported. The first derivative, 6,10-Dichloro-17-azadibenzo[a,n]triphenodithiazin-5,11-dione10 was obtained by a base-catalyzed reaction of 2,6-diaminopyridine-3,5-dithiol 5and 2,3-dichloro-1,4-naphthaquinone 9, while that of the second derivative, 7,9,15,17-tetraamino-6,8,16,18,25-pentazadibenzo[a,n]di([1,4]benzothaizino[3,2-c,l])triphenodiathizine (11) was achieved by the reaction of two moles of 2, 4, 6-triaminopyrimidine-3-thiol (8) and one mole compound (10) under the same reaction conditions.. The assigned structures to the above synthesized compounds were done on the basis of spectroscopic analysis.
Monoaza, Pentaaza, Triphenodiathiazin, Triaminopyrimidine-3-thiol, Phenothiazine.
