Crystals of the title compound, 2C(26)H(18)N(4)O(2)·C(7)H(8), were obtained from the reaction of 8-hydroxy-quinoline with 1,2-phenyl-enediamine in methanol and recrystallized from toluene. The compound contains three essentially planar ring systems: the benzimidazole ring (r.m.s. deviation = 0.039 Å) and two 8-hydroxy-quinoline rings (r.m.s. deviations of 0.0056 Å in both rings). The benzimidaz...

Reaction of pentafluoropyridine with 2 or 8-hydroxyl-quinoline under basic conditions in acetonitrile gives 4-oxy quinoline 2,3,5,6-tetrafluoropyridine derivatives in good yields. All the compounds were characterized using 1H, 13C, 19F-NMR and MS spectroscopy.

46 Desai et al synthesized a series of new quinoline derivatives and evaluated their pharmacological activity as antimicrobial agents. Quinoline is a heterocyclic aromatic organic compound itrogen atom as part of the ring system, with the chemical formula . It can also be named as, benzopyridine, benzo[b]pyridine, 1benzazine and benzazine. featuring n C H N 9 7 It is a colorless hygroscopic liq...

Quinoline-8-ol, one of the most popular and versatile organic reagents, is known to react with several metals, because it has both a basic nitrogen and a phenolic group. Hence, quinoline-8-ol and its derivatives have been widely used as chelating and/or sorbent extraction agents in on-line flow injection analysis (FIA) along with a suitable detection technique. The state of the art for using qu...

In the title coordination polymer, [Ag(C(10)H(6)NO(2))](n), the Ag(I) cation is coordinated by two O atoms and one N atom from three 6-quinoline-carboxyl-ate anions in a distorted T-shaped AgNO(2) geometry, in which the O-Ag-O angle is 160.44 (9)°. The 6-quinoline-carboxyl-ate anion bridges three Ag(+) cations, forming a nearly planar polymeric sheet parallel to (101). The distance between Ag(+...

The mol-ecule of the title hydrate, C(16)H(11)ClFN(3)·H(2)O, is slightly twisted, as indicated by the dihedral angle of 9.55 (10)° formed between the quinoline ring system and the benzene ring. The conformation about the C=N double bond is E, and the amine-H atom is oriented towards the quinoline residue. In the crystal structure, the water mol-ecule accepts an N-H⋯O and makes two O-H⋯N(quinoli...

Two independent mol-ecules comprise the asymmetric unit of the title compound, C(20)H(16)ClNO, which differ in the orientation of the chalcone residue with respect to the quinoline ring [the C-C-C(=O)-C torsion angles are 69.5 (2) and 86.0 (2)°]. The configuration about each of the ethyl-ene bonds [1.342 (2) and 1.338 (2) Å] is E. The three-dimensional crystal structure is stabilized by a combi...

Two metabolites have been isolated from the fermentation broth of a new species of Kitasatoa, Kitasatoa griseophaeus. These alkaloids have been identified as quinoline-2-methanol and quinoline-2-methanol acetate. The former exhibits hypoglycemic activity in the rat.
