A series of new Ru(II) complexes of 8-hydroxy quinoline-2-carboxyaldehyde hydrazone of the general formula [RuH(CO)(EPh3)2L] (1–6) (E = P or As, L = N’-((8-hydroxyquinolin-2-yl)methylene)thiophene-2-carbohydrazide (HQ-THy), N’-((8-hydroxyquinolin-2-yl)methylene)isonicotinohydrazide (HQ-IHy), N’-((8-hydroxyquinolin-2-yl)methylene) benzohydrazide (HQ-BHy)) have been synthesized. They have been characterized by elemental analysis, IR, NMR (1H, 13C & 31P) and ESI-MS spectral methods. Further, structures of two of the complexes have been determined by single crystal X-ray diffraction technique which revealed a pseudo octahedral geometry with the coordination of the quinoline nitrogen and quinoline oxygen atoms of the ligand. All the new complexes have been employed as efficient catalysts in N-alkylation reactions for the synthesis of tertiary amines by the coupling of secondary amines with aromatic primary alcohols at low catalyst loading with maximum yields. In addition, the effects of substituents on the ligands, different solvents as well as bases and amounts of catalyst loading on the catalytic activity of the complexes have been thoroughly investigated. Complex 1 was found to be efficient catalyst towards N-alkylation of alcohols with the amine. Further, a variety of secondary amines and aromatic (hetero) primary alcohols with various functional groups have also been successfully used in the N-alkylation reactions and it has been found that only one equivalent of the alcohol was consumed in the process.

The invention discloses a dysprosium complex constructed with a 8-hydroxyquinoline acylhydrazone derivative as a ligand, and a synthesis method and an application of same. The chemical formula of the complex is [Dy(HL)(L)].2H2O, wherein the L refers to 2-formyl-8-hydroxyquinoline benzoylhydrazone with a hydrogen atom on a hydroxyl group and a hydrogen atom on acylhydrazone nitrogen eliminated and with two units of negative charges; and the HL refers to 2-formyl-8-hydroxyquinoline benzoylhydrazone with a hydrogen atom on a hydroxyl group eliminated and with one unit of negative charge. The synthesis method of the complex includes the steps of: dissolving Dy(NO3)3.6H2O and the 2-formyl-8-hydroxyquinoline benzoylhydrazone in a mixed solvent, regulating the pH of the solution to 7.5-8.1; carrying out a reaction to the mixed solution under a heating condition, cooling a reaction product until a crystal is separated out to obtain the product, wherein the mixed solvent is a composition of methanol/water. The complex, at low temperature, shows a field-induced slow-relaxation magnetic behavior.

In continuation of our program aimed at the discovery and development of efficient insecticidal agents, a series of quinoline-based hydrazone derivatives were synthesized and evaluated as insecticidal agents against three-day-old larvae of Spodoptera litura (Noctuidae: Lepidoptera), a polyphagous insect pest of many important crops, in vivo at 1 mg mL1. In particular, compounds 3c, 3e, 4g, 4h, and 6f showed potent insecticidal activity with 7 day mortality rates greater than 93%, and were comparable to that of the positive control toosendanin.
