El Maghraby, M. A. published the artcileSymmetrical dicationic cyanine dyes incorporating pyrazolo-pyrano oxazone (pyrimidine) moiety, Formula: C12H14IN, the publication is Aswan Science & Technology Bulletin (1991), 3-14, database is CAplus.
3-Amino-6-methyl-5-aryl-2,5-dihydropyrano[2,3-c]pyrazole-4-carbonitriles were acid hydrolyzed to the corresponding -4-carboxylic acids (55-57% yield), which were condensed with Ac2O to give 3,7-dimethyl-4-aryl-1-acetylpyrazolopyranooxazinones (58-61%); the corresponding pyrimidinones (42-45%) were obtained using ammonia. Oxidation of these products with SeO2 converted the 2 Me groups (58-64%) to CHO groups. Condensation with α-picoline or quinaldine ethiodides gave 45-65% I (X = Cl, NO2; Y = 1-ethylpyridinium-2-yl iodide, 1-ethylquinolinium-2-yl iodide; Z = O, NH). The visible absorption spectra of I were recorded.
Aswan Science & Technology Bulletin published new progress about 606-55-3. 606-55-3 belongs to iodides-buliding-blocks, auxiliary class Quinoline,Salt, name is 1-Ethyl-2-methylquinolin-1-ium iodide, and the molecular formula is C12H14IN, Formula: C12H14IN.
