In the title compound, C(27)H(18)Cl(2)N(2)O(2), the 2-chloro-quinoline and 6-chloro-quinoline rings are almost planar, with maximum deviations from their mean planes of 0.072 (1) and 0.044 (1) Å, respectively, for the Cl atoms. The inter-planar angle between these rings is 14.36 (5)°. The inter-planar angle between the 6-chloro-quinoline and phenyl rings is 66.00 (8)°. In the crystal, mol-ecule...

Many quinolones, substituted quinolines and thiones are well known for their biological activity. The redox characteristics of such biological substances may provide valuable information about the redox behaviour in living systems. The present paper is aimed at carrying out a methodical cyclic voltammetric investigation of the peak potential values of 4-methyl/phenyl -3vinyl quinoline-2(1H) one...

Photoinduced cyclization of o-alkenylaryl isocyanides with (PhS)2 in the presence of (PhTe)2 affords the corresponding bisthiolated indene derivatives in good yields via radical cyclization process by thio radical. The procedure can be applied to the construction of tetracyclic systems by using bis(o-aminophenyl) disulfides in place of (PhS)2. In sharp contrast, when o-alkynylaryl isocyanides a...

In the title compound, C19H15N3O2·H2O, the oxa-diazole ring and the quinoline unit are almost coplanar, making a dihedral angle of 7.66 (8)°. The dihedral angle between the benzene ring and the quinoline system is 25.95 (8)° while that between the benzene and the oxa-diazole rings is 18.88 (9)°. The water mol-ecule is hydrogen bonded to an oxa-diazole N atom and to the quinoline N atom. In the ...

In the reaction of 8-hy-droxy-quinoline, 2-methyl-8-hy-droxy-quinoline and stannic chloride, the 2-methyl-8-hy-droxy-quinoline is protonated, yielding the disolvated title salt, (C(10)H(10)NO)[SnCl(4)(C(9)H(6)NO)]·2CH(3)OH. The Sn(IV) atom in the anion is N,O-chelated by the hy-droxy-quinolinate in a cis-SnNOCl(4) octa-hedral geometry. In the crystal, the cation, anion and solvent mol-ecules ar...

In this study a one step method for the preparation of substituted anilides of quinoline-2-carboxylic acid was developed. This efficient innovative approach is based on the direct reaction of an acid or ester with substituted anilines using microwave irradiation. The optimized method was used for the synthesis of a series of eighteen substituted quinoline-2-carboxanilides. The molecular structu...

In the title compound, [Cu(C(34)H(24)N(4)O(2)S(2))] or [Cu(bqdapte)], where H(2)bqdapte is 1,2-{bis-[2-(quinoline-2-carboxamido)-phen-yl]sulfan-yl}ethane, the Cu(II) ion is coordinated to the dianionic hexa-dentate bqdapte(2-) ligand by two amide and two quinoline N atoms and two thio-ether S atoms. In the observed conformation of the hexa-dentate ligand, the quinoline rings attain positions re...

In the title compound, C18H13F2NO2, the two rings of the quinoline system are fused almost coaxially, with a dihedral angle between their planes of 2.28 (8)°. The plane of the attached benzene ring is inclined to the plane of the quinoline system by 7.65 (7)°. The carboxyl-ate group attached to the quinoline system is in an anti-periplanar conformation. There is a short intra-molecular C-H⋯O co...
