An efficient silver-catalyzed d-regioselective C(sp(3))-H heteroarylation of free alcohols has been developed. Various alcohols reacted with quinolines, isoquinoline, pyridines, pyrimidine, phthalazine, 4-hydroxyquinazoline, acridine, quinoxaline and pyrazine to give the corresponding C(sp(2))-H alkylation products in 31-89% yields. Notably, all types (1 degrees, 2 degrees, and 3 degrees) of d-C(sp(3))-H bonds in the alcohols could be regioselectively activated. This protocol provides a platform to access divergent functionalizations of alcohols and heteroaryls by forming the challenging d-selective C(sp(3))-C(sp(2)) bond.

In the present study, a new hydrazone ligand (2-((2-phthalazin-1-yl)hydrazono)methyl)phenol) prepared by condensation of hydralazine (1-Hydralazinophthalazine) with salicylaldehyde (SAH). The synthesized SAH-hydrazone and its metal complexes have been characterized by elemental analyses, IR, H-1 NMR, solid reflectance, magnetic moment, molar conductance, mass spectra. UV-vis and thermal analysis (TGA). The analytical data of the complexes show the formation of 1:1 [M:L] ratio, where M represents Ni(II), Co(II) and Cu(II) ions, while L represents the deprotonated hydrazone ligand. IR spectra show that SAH is coordinated to the metal ions in a tridentate manner through phthalazine-N, azomethine-N and phenolic-oxygen groups. The ligand and their metal chelates have been screened for their antimicrobial activities using the disc diffusion method against the selected bacteria and fungi. Proton-ligand association constants of (SAH) and the stepwise stability constants of its metal complexes are determined potentiometrically in 0.1 M NaNO3 at different temperatures and the corresponding thermodynamic parameters were derived and discussed. The order of -Delta G degrees and -Delta H degrees were found to obey Mn2+ < Co2+ < Ni2+ < Cu2+, in accordance with the Irving-Williams order. The complexes were stabilized by enthalpy changes and the results suggest that the complexation is an enthalpy-driven process. The concentration distribution diagrams of the complexes are evaluated.

The chemistry of phthalazine derivatives has been of increasing interest since many of these compounds have found many chemotherapeutic applications. So this study aims to synthesize a library of phthalazine derivatives and to investigate their anti-inflammatory and anti-proliferative activities. Sixteen new phthalazinone derivatives (2a-p) were synthesized and tested for their in vitro antiproliferative and in vivo anti-inflammatory activities. All the synthesized compounds were identified and characterized by IR, H-1 NMR, C-13 NMR spectroscopy, and MS. Two compounds, 2b and 2i, showed significant anti-inflammatory activity comparable with that of the standard drug etoricoxib in the carrageenan-induced rat paw edema model at 3 and 5h, respectively.

The vaporization enthalpy of imidazo[1,2-a]pyrazine is evaluated by correlation gas chromatography using two sets of standards and by transpiration. Vaporization enthalpies were evaluated using heterocyclic standards with dipole moments that vary from 0 to 3.0 D and using standards with dipole moments > 3.0 D. A value of (70.7 +/- 1.0) kJ.mol-1 measured by transpiration compares to (67.9 +/- 1.4) kJ.mol1 measured by correlation gas chromatography using standards characterized by dipole moments > 3.0 D. The results suggest that imidazo[1,2-a]pyrazine is a member of this series of compounds whose vaporization enthalpies exceed those less polar heterocycles by a fairly constant amount, (6.9 +/- 0.3) kJ.mol-1, in this case by (5.9 +/- 3.0) kJ.mol(-1) using the less polar heterocycles. The crystal structures of phthalazine, another member of the polar series, and of imidazo[1,2-a]pyrazine were determined to examine whether p-p stacking, present in the solid state of two other members of the polar series, was a characteristic of this series. If present in the liquid, p-p stacking could offer a possible explanation for the vaporization enthalpy differences observed. The sublimation enthalpy of imidazo[1,2-a]pyrazine was also evaluated.

Regarding the green chemistry’s goals, silica-coated magnetite nanoparticles (MNPs) open up new avenue to introduce an amazing and efficient system for facilitating catalyst recovery in different organic reactions. Therefore, in this paper the preparation of sulfuric acid functionalized silica-coated magnetite nanoparticles with core-shell structure (Fe3O4@silica sulfuric acid) are presented by using Fe3O4 spheres as the core and silica sulfuric acid nanoparticles as the shell. The catalyst was characterized by infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) spectroscopy, and vibrating sample magnetometer (VSM). Ability of this nano-magnetic solid acid catalyst in the one-pot three-components condensation reaction of phthalhydrazide, aromatic aldehydes and cyclic or acyclic 1,3-diketones are also described.

The poly(tetraphenyl ether ketone sulfone)s (PTPEKSs) were synthesized from 1,2-bis(4-fluorobenzoyl)-3,4,5,6-tetraphenyl benzene (BFBTPB) and bis(4-fluorophenyl) sulfone with bis(4-hydroxydiphenyl) sulfone in sulfolane. The synthesis of poly(tetraphenyl phthalazine ether sulfone)s (PTPPESs) was carried out via an intramolecular ring-closure reaction of dibenzoylbenzene moiety with hydrazine monohydrate. The PTPPES-QAHs [poly(tetraphenyl phthalazine ether sulfone-quaternary ammonium hydroxide)]s were synthesized via chloromethylation of PTPPES, quaternization with trimethylamine, and followed by an anion exchange of tetra-quaternary ammonium chloride polymers with KOH. Different contents of quatemized unit in PTPPES-QAH (15, 20, 25 mol% of BFBTPB) were studied by FT-IR, H-1 NMR spectroscopy, and thermogravimetric analysis (TGA). Sorption experiments were conducted to observe the interaction of quatemized polymers with water. The ion exchange capacity (IEC), ion conductivity and cell performance of PTPPES-QAH were evaluated with increasing the degree of quaternization.
