Salvador, Maria A. published the artcileDelocalized cationic azo dyes containing a thiazole moiety, Related Products of iodides-buliding-blocks, the publication is Tetrahedron (2008), 64(2), 299-303, database is CAplus.
Several new delocalized cationic azo dyes incorporating a bathochromic thiazole moiety have been prepared in moderate to good yields. The synthesis involved the Knoevenagel condensation of an intermediate azo compound, bearing a terminal formyl group, with methylenic bases generated in situ from benzazolium and quinolinium salts. All dyes display strong absorption around 700 nm and have shown neg. solvatochromic behavior. The possible application of the dyes as sensitizers for photodynamic therapy was briefly discussed.
Tetrahedron 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, Related Products of iodides-buliding-blocks.
