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...

amaryllidaceae is a well-known family for its high alkaloidal content. these alkaloids comprise a unique group of bases that have been found to occur in this family. the amaryllidaceae alkaloids represent a large and still expanding group of isoquinoline alkaloids, the majority of which are not known to occur in any other family of plants this article reports on the phytochemical investigation ...
