A new protocol for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives is described via a one-pot three-component condensation reaction of phthalhydrazide, dimedone or 1,3-cyclohexanedione and aromatic aldehydes catalyzed by SnO2 nanoparticles as a heterogeneous catalyst under solvent-free conditions. The SnO2 nanoparticles (NPs) were characterized by FT-IR, X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray analyzer (EDAX). The advantages of the protocol are the shorter reaction time, simple work-up procedure and reusable catalyst. [GRAPHICS] .

Two cyclometalated dimeric from complexes, [{Ir(mu-Cl)(mu-ppa)(dmppa)}(2)] (dimer 1) and (dmppa)Ir(mu-Cl) (mu-ppa)Ir(ppa) (dimer 2) (dmppa = 1-(2.6-dimethylphenoxy)-4-phenylphthalazine, ppa =1-hydroxy1-4-phenylphthalazine), containing the bridging phthalazine ligands and bridging chlorides have been synthesized and fully characterized. Dimer 1 can form a noncovalently linked crystalline porous frameworks. The emission wavelength of dimer 1 in CH2Cl2 solution was 596 nm and the further hydrolysis of phenolic groups red shift the emission of dimer 2 to 634 nm. Two dimers have relatively high quantum efficiency, i.e., ca. 0.21 for dimer 1 and 0.3 for dimer 2 in CH2Cl2 solution. (C) 2011 Elsevier B.V. All rights reserved.

In this work we present the synthesis, and experimental and theoretical analysis of a binuclear nickel(II) complex coordinated to a new phthalazine dihydrazone-based ligand. Single-crystal X-ray diffraction analysis of the metal complex shows that the coordination geometry around each nickel(II) atom is distorted octahedral. DFT calculations predict that the magnetic exchange coupling constant of the binuclear nickel(II) complex is predominantly anti-ferromagnetic. [GRAPHICS] .

Recently, we described the first inverse electron demand Diels-Alder reaction of 1,2-diazene catalyzed by a bidentate Lewis acid. Herein we investigate 1,2-phenylenediboronic esters as potential catalysts for this transformation offering higher stability and easier handling than the currently used boranthracene derivatives. Different 1,2-phenylenediboronic esters were prepared and their ability to form bidentate coordination complexes with phthalazine was analyzed. Although a 1:1 complex was observed, X-ray analysis revealed binding only in a monodentate fashion.

A new complex of nickel(II) with 1-(2-[(5-methylfuran-2yl)methylene)] hydrazono) phthalazine HL (1) has been synthesized and characterized by elemental analysis, IR, electronic spectra, TGA, H-1 and C-13 NMR spectroscopy. The crystal structures of the free ligand and its complex have been determined by single crystal X-ray diffraction techniques. In the complex the hydrazone ligand chelates to the nickel(II) through nitrogen atoms in a bidentate manner. The antifungal activity of the ligand and its nickel(II) complex 3 was studied against Aspergillus niger, Aspergillus flavus and Candida albicans. The results revealed modest activity of the complex (3) against the tested organisms with inhibition zones of 14, 14 and 13 mm, compared to the free ligand 1 with inhibition zones of 11 mm each for A. niger, A. flavus and C. albicans respectively.

With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing. 1008-72-6, Name is Sodium 2-formylbenzenesulfonate, SMILES is O=S(C1=CC=CC=C1C=O)([O-])=O.[Na+], in an article , author is Jiang, Lilin, once mentioned of 1008-72-6, Quality Control of Sodium 2-formylbenzenesulfonate.

Cu@Fe3O4 MNPs as novel nanomagnetic reagents were prepared to investigate their catalytic behavior in the preparation of tetrahydrobenzimidazo[2,1-b]quinazolin-1(2H)-ones, as important biologically active compounds. Then, characterization of the synthesized nanoparticles was performed using different methods including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) analysis, thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), energy dispersive X-ray (EDX), and scanning electron microscopy (SEM). All reactions were performed with small amounts of the Cu@Fe3O4 MNPs under solvent-free conditions. After completion of the reaction, because of the magnetic nature of the nanocatalyst, they could be simply separated with an external magnet and easily reused with no considerable decrease in the catalytic behavior even after seven runs.
