Abstract: | Glutaconic dialdehyde dianil salts, the ,-carbon atoms of which are included in dihydropyran, dihydrothiapyran, or N-methyltetrahydropyridine rings, were synthesized. Tricarbocyanine dyes with epoxydimethylene, epithiodimethylene, or N-methylepiminodimethylene groupings were synthesized by condensation of the dianil salts with a 2-methylbenzothiazole quaternary salt. The color of the dyes is discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 175–178, February, 1976. |
