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.

The title compound, C(12)H(10)N(2)O, is approximately planar. The angle between the quinoline and 4,5-dihydro-oxazole ring systems is 11.91 (12)°. The mol-ecules pack into a herringbone array with no significant π-π inter-actions. The dihydro-oxazole N and O atoms are disordered over two positions, with almost equal site occupancy factors.

A new rhodamine-quinoline based dyad has been synthesized. It shows a highly selective response to Cd(2+) in the presence of other competing metal ions in aqueous media (pH = 7.1). The detection limit of the sensor is in the 10(-7) M level.

In the title complex, [Ni(C(10)H(6)NO(2))(2)(CH(3)OH)(2)], the Ni(II) ion lies on an inversion center and is coordinated by two quinoline-2-carboxyl-ate ligands in the equatorial sites and two axial methanol ligands, forming a distorted octa-hedral environment. In the crystal, mol-ecules are linked via O-H⋯O hydrogen bonds into a two-dimensional network parallel to (10[Formula: see text]).

Background: The 153Sm-[tris(1,10-phenanthroline) Samarium(III)]complex (153Sm-PL3) was prepared in view of development of targeting therapeutic compounds for malignancies, and interesting in-vitro anti-tumor activities of lanthanide phenanthroline complexes,.
