A reaction between equimolar amounts of cis-[PdCl2(CNCy)2] (1) and indazole (HInd, 2) or 5-methylindazole (HInd(Me), 3) proceeded in refluxing CHCl3 for ca. 6 h affording the aminocarbene species cis-[PdCl2{C(Ind)=N(H)Cy}(CNCy)] (4) or cis-[PdCl2{C(Ind(Me))=N(H)Cy}(CNCy)] (5) in good (72-83%) isolated yields. Complexes 4 and 5 were characterized by elemental analyses (C, H, N), HR ESI(+)-MS, IR...

New heterocyclic compounds contain triazole ring (play very important role in photostabilization as UV absorber) synthesized by reaction between the di Schiff base (compound 3) with aromatic alkyl halide (Benzyl bromide) and shows there activity photostabilizer for polystyrene through exposure to UV-Light (300 hours). Finally Infrared spectroscopy, 1H-NMR, 13C-NMR instrumental methods were used...

A series of novel alkyl derivatives (2–5a,b) and 1H-1,2,3-triazole analogues (7a–k) Meldrum’s acid were synthesized in a highly effective way by using “click” chemistry screened for vitro α-glucosidase inhibitory activity to examine their antidiabetic potential. 1H NMR, 13C-NMR, high-resolution electrospray ionization mass spectra (HR-ESI-MS) used analyze each the newly compounds. Interestingly...

The synthesis, characterization, and photophysical properties of two novel ligands, 5LINMe-1,2-HOPO (1) and H(2,2)-1,2-HOPO (2), which utilize the 1,2-HOPO chelate as a sensitizer for Eu(III) are reported. In addition, the former ligand was structurally characterized as the Eu(III) complex by X-ray crystallography. The [Eu(1)2]- complex of the tetradentate ligand (1) is stable in aqueous soluti...

New S-substituted 4-alkyl-5-((3-(pyridin-4-yl)-1H-1,2,4-triazole-5-yl)thio)methyl)-4H-1,2,4-triazole-3-thiol derivatives have been designed, synthesized and studied their antimicrobial activity on 11 standard Gram-positive Gram-negative microorganism strains. Their spectral physicochemical parameters were established using modern comprehensive methods of analysis, including 1 H NMR spectroscopy...
