Azo dye of quinoline named 5-(3-pyridylazo)-8-hydroxyquinoline (PAHQ) was prepared via coupling reaction diazonium salt 3-aminopyridine and 8-hydroxyquinoline. he PAHQ characterized by elemental analysis, mass spectroscopy 1H-NMR. The complexes were under 2:1 (L:M) mole ratio. infrared spectroscopy, UV-Vis, molar conductance, magnetic susceptibility. IR spectra data indicate that ligand is bid...

The reaction of some carbocyclic and heterocyclic Schiff bases with the synthesized 1-bromo, 4-[4-(4-nitrophenylazo) phenoxy] butane and formation of novel linear azo-azomethine compounds in good to excellent yields were investigated. The compounds were fully characterized by UV-Vis, FT-IR, 1H NMR spectroscopic techniques and elemental analysis. Effects of various solvents on their visible abso...

A new azo-azomethine chemosensor containing active phenolic sites, H2L, has been designed and synthesized for rapid detection of inorganic fluoride over the other anions, such as Clˉ, Brˉ, Iˉ, AcOˉ, H2PO4ˉ, NO3ˉ, N3ˉ in DMSO/water (90/10) media. The 1H NMR titration revealed that the colorimetric response was considered to be the direct consequence of hydrogen-bond formation between phenolic gr...

The novel ligand 2-[2'-(6-methoxybenzothiazolyl)azo]-3,5-dimethyl benzoic acid (6-MBTAMB), derived from 2-amino-6-methoxy benzothiazole, has been used to synthesize a series of new metal complexes Ag(I), Pt(IV) and Au(III). were characterized by elemental analyses (CHNS), molar conductivity, crystal structure (XRD), spectroscopic techniques: FT-IR, 1H NMR, 13C UV–Vis, mass spectra, thermal anal...

1,3-Dipolar cycloaddition reactions of azomethine ylides play an important role in the synthesis of highly substituted pyrollidines which are found in the structures of many important natural products and pharmaceuticals . Using this chemistry, four chiral centers can be created in a single step. The asymmetric version of this reaction has been tried both with achiral azomethine ylides and chir...

–A novel series of 2-phenyl-5-sulpha/substituted-3-phenyl substituted azo indoles have been synthesized and tested as an antifertility activity in mature albino mice. The tested compounds showed significant antifertility activity. Keywords––Synthesis, Antifertility activity, Indore, Azo indoles, chemical analysis.
