The first example of oxidant-free cobalt-catalyzed synthesis five-membered spirocycles is reported from benzimidates and maleimides utilizing nitrobenzene as promoter. In contrast to previously known oxidative C–H functionalization reactions, this transformation occurs efficiently in the absence oxidant accompanied by liberation hydrogen. spiro-lactams were readily achieved hydrolysis as-prepared spirocyclic compounds. Cp*Rh(III) catalyst shows poor reactivity.
A novel chelating resin, polyacrylonitrile-2-aminothiazole (PAN-AT), was synthesized simply by the reaction of polyacrylonitrile with 2-aminothiazole. Optimization PAN-AT synthesis carried out at different temperatures, molar ratios reagents, and time intervals in N,N-dimethylformamide (DMF) using response surface methodology (RSM) for first attempt. The functional group capacity (the content group) percentage conversion prepared under optimum conditions were 3.94 mmol/g 41.10%,...
The mechanisms and origins for the Pd- Ni-catalyzed regioselective hydrosilylation of allene have been investigated by means density functional theory (DFT) calculations. free-energy profiles reactions with small bulky N-heterocyclic carbene (NHC) ligands are calculated to determine mechanism regioselectivities. calculation results show that different metals (Ni vs Pd) lead regiochemical reversals allene. allylsilane is major product via palladium catalysis NHC ligand, while vinylsilane...
As a kind of excellent diesel-blending component, polyoxymethylene dimethyl ethers (PODEn) have received widespread attention. Herein, Al-SBA-15 molecular sieves with different Si/Al ratios and pore sizes were synthesized used to investigate the catalytic performance for synthesis from methylal trioxane. X-ray diffraction, N2 adsorption–desorption, scanning electron microscopy, transmission fluorescence, 27Al NMR characterize structures obtained catalysts. Ammonia temperature-programmed...
Abstract A highly Z ‐selective phosphorylation by Manganese(III) acetylacetonate‐mediated cross‐dehydrogenative‐coupling of enamides and phosphine oxides has been developed under mild conditions. The reaction shows broad substrate scope functional group compatibility. DFT studies revealed that the formation ‐products is presumably due to presence an intramolecular hydrogen bond. β ‐Aminophosphine could be readily obtained reduction hydrolysis product. magnified image
A novel chelating material PS-ATD resin applied to the efficient separation and recovery of platinum from aqueous solutions.
A new chelating resin, polystyrene-2-aminothiazole (PS-AT), was synthesized via one-step reaction by grafting 2-aminothiazole in a chloromethylated polystyrene polymer. Its structure characterized elemental analysis and infrared spectroscopy. Batch experiments were applied to investigate the adsorption properties of PS-AT for Au(III) ions. The resin exhibits an excellent selectivity ions presence Ni(II), Cu(II), Cd(II), Co(II) maximum capacity obtained at 308 K 733.8 mg/g. kinetic...
A one-pot synthesis of fluorescent 2,4-dialkenylindoles by rhodium-catalyzed dual C–H bond alkenylation indoles.
Sulfonic acid-functionalized mesoporous SBA-15 with different sulfur loading was synthesized and used to investigate the catalytic performance for PODE<sub>n</sub> synthesis.
In this study, green chloromethylated polystyrene bead–1,3-diaminourea (PS–DU) which was intended to adsorb copper ions synthesized from (PS-Cl) and 1,3-diaminourea (DU).
