Yazdanseta, Saeed published the artcileAnchoring Cu (II) on Fe3O4@ SiO2/Schiff base: a green, recyclable, and extremely efficient magnetic nanocatalyst for the synthesis of 2-amino-4H-chromene derivatives, Synthetic Route of 86-51-1, the main research area is preparation copper iron oxide silica Schiff green recyclable nanocatalyst; thermal decomposition copper iron oxide silica Schiff recyclable nanocatalyst; aromatic aldehyde preparation; copper iron oxide silica Schiff recyclable nanocatalyst.

Abstract: a novel water-soluble Salen type Cu(II) Schiff base complex functionalized silica-coated magnetite nanoparticles [Fe3O4@SiO2/Schiff base of Cu(II)] was synthesized and characterized. First, an immobilized water-soluble Schiff base was synthesized from the condensation reaction between 3-amino Pr triethoxy silane (APTES) functionalized silica-coated magnetite nanoparticles and a water-soluble aldehyde (sodium salicylaldehyde-5-sulfonate monohydrate). After that, functionalized Schiff base was converted to functionalized Cu(II) Schiff base complex as the result of reaction with Cu(II) acetate tetrahydrate. The structural and magnetic properties of the prepared compounds were identified by FTIR, XRD, SEM, EDX, TEM, VSM, and TGA. The catalytic activity of the novel nanocatalyst was studied for the preparation of 2-amino-4H-chromene derivatives through an one-pot, three-component reaction of dimedone, aromatic aldehydes, and malononitrile, in the presence of catalytic amounts of the Fe3O4@SiO2/Schiff base of Cu(II) nanocatalyst in water and at room temperature The 2-amino-4H-chromene derivatives were obtained in good to excellent yields. Furthermore, because of the solubility of metal Schiff base complexes in water, the nanocatalyst dispersed in water easily without using ultrasonic or shaker.

La, Ming published the artcileMonodentate Transient Directing Group-Assisted Palladium-Catalyzed Direct ortho-C-H Iodination of Benzaldehydes for Total Synthesis of Hernandial, Computed Properties of 86-51-1, the main research area is benzaldehyde palladium catalyst regioselective iodination; iodo benzaldehyde preparation.

The first palladium-catalyzed direct o-C-H iodination of benzaldehydes was successfully developed with the assistance of com. available 2,5-bis(trifluoromethyl)aniline as the optimal monodentate transient directing group (MonoTDG). Moderate to excellent yields and good selectivity were achieved for a broad substrate scope under mild conditions. More importantly, the synthetic application was demonstrated by a concise two-step total synthesis of the natural product hernandial, which was accomplished by merging this new MonoTDG-assisted C-H iodination and subsequent copper-catalyzed cross-coupling.

Fiore, Ambra Maria published the artcileMild and efficient synthesis of secondary aromatic amines by one-pot stepwise reductive amination of arylaldehydes with nitroarenes promoted by reusable nickel nanoparticles, Name: 2,3-Dimethoxybenzaldehyde, the main research area is nitrobenzene aryl aldehyde polymer supported nickel reductive amination; secondary amine preparation.

The one-pot stepwise reductive amination of arylaldehydes with nitroarenes was described, using reusable nickel nanoparticles (Ni-pol) as catalyst and NaBH4 as mild, inexpensive and safe reducing agent. The proposed catalytic system holds several advantages such as the use of a non-precious and earth-abundant metal, the facile separation of the catalyst from the reaction mixture by centrifugation, excellent stability towards air and moisture, very mild reaction conditions, good recyclability, broad substrate scope with good to excellent yields and easy scalability. FESEM analyses indicate that the active species were cubic nanocrystals of Ni in the average cross section value of 35 nm with a quite narrow (25-45 nm) and monomodal distribution, which becomes bimodal with the recycling reactions but without agglomeration.

Tvspv, Satya Guru published the artcileExcellent catalytic activity of ethylenediamine stabilised oxalate ligated aluminium coordination complex for synthesis of novel benzoquinolines, Quality Control of 86-51-1, the main research area is aluminum oxalate oxo complex preparation crystal structure heterocyclization catalyst.

Two-dimensional supramol. structure of oxalate ligated Al(III) coordination complex, (C2H10N2)2.[Al2(μ-O2)(oxalate)4]•2H2O (Al-Ox) was synthesized hydrothermally and determined the structural features with single-crystal x-ray diffraction studies. Unique oxo bridged dinuclear Al(III) clusters were established and each Al(III) atom bonded with two units of oxalate ligand. In the dinuclear Al(III) structure, two Al(III) atoms were separated with a bond distance of 2.8702 Å. Unsaturated metal centers creation upon activation acts as Lewis acid sites and ethylenediamine with a strong basic character in the structure remarkably facilitate an efficient and economic strategy for better organic transformations. The Lewis acid-base character catalytic efficacy of the complex is explored in the tandem multi-component synthesis of benzoquinoline-2-carbonitrile moieties. The synergy between the exceptional Lewis acidic and basic properties of Al-Ox contributed to its excellent catalytic activity in the generation of five new benzoquinoline-2-carbonitriles in impressive yields (92-96%) in short reaction time (∼15 min) in a simple one-pot protocol, in ethanol. Recyclability with consistent activity (>5 times) is the added advantage.
