“…This could be explained by trimerisation of cyano compounds 61a-c into the corresponding 1,3,5triazine derivatives. 13 Appearance of fragments, corresponding to MH + , M 2 H + , and M 3 H + , in the FAB mass spectrum of compound 61a, could be in agreement with the trimeric structure. However, the absence of a typical 1,3,5-triazine carbon signal at ca.…”

S)-3-(Dimethylamino)methylidene-5-benzyltetramic acid derivatives 4a and 4b were prepared in three steps from N-protected (S)-3-phenylalanines 1a and 1b, respectively. Similarly, N- [N-(benzyloxycarbonyl)glycyl]glycine (1c) was transformed into the enaminone 4c. Acid-catalysed coupling of enaminones 4a-c with aliphatic, aromatic, and heteroaromatic primary amines 5-34 afforded the corresponding N(3¢)-substituted 3-aminomethylidenetetramic acid derivatives 35-64 in 29-96% yields.

“…Thus introducing a reactive moiety in the disperse dye structure have a great advantage which improve the buildup of the dye in nylon fabrics throw its covalent bond with the fiber, this type of dyes known as reactive disperse dyes which have the favorable characteristics of both disperse and reactive dyes [9][10][11]. Triazinyl derivatives are very important compounds not only as dye intermediate but also in the area of preparing functionalized 1,3,5-Triazine derivatives which covering a wide area of application such as organic light emitting diodes (OLED's), medical, textile, plastic, and rubber industries [12][13][14][15][16][17][18][19][20].…”

A NEW two reactive disperse dyes based on a hybrid structure of isatin and benzanthrone or anthraquinone via 1, 3, 5 triazine spacer were prepared. The prepared compounds were characterized by 1 H-NMR, mass spectrometry and elemental analysis. The UV/vis absorption spectra and emission spectra were measured in N, N-dimethylformamide (DMF) solution at room temperature, the effects of substituent's on the emission spectra of these compounds were interpreted. The dyeing application of the prepared dyes on wool and polyamide-6 fabrics at various concentrations of dye and different pH were investigated as well as the exhaustion and dye fixation were studied. The antibacterial activity of the prepared reactive disperse dyes were studied against different kind of bacteria such as Staphylococcus aureus (Gram-positive bacteria) and Escherichia coli (Gram-negative bacteria). The antibacterial affinity of the prepared dyes was exhibit a significant effect compared with selected antibiotics as reference standard. The fastness properties of the dyed fabrics were studied which showing excellent wash fastness, rubbing and perspiration fastness as well as high stability to light.

“…Besides they are also used as pesticides, dyestuffs, optical bleaches, explosives, and surface active agents [1][2][3][4][5][6] . Quinoline is one of the most important heterocyclic compounds, which is used as a feedstock for the preparation of hydroxy quinoline sulfate, niacin; for manufacture of dyes and as a solvent for resins and terpenes.…”
