سیلیکاژل حامل سریک سولفات 2(sio2-ce(so4 (سریک سولفات تثبیت شده بر روی سیلیکاژل) به آسانی از مواد اولیه ی مربوطه تهیه شد و به عنوان کاتالیست ناهمگن برای تهیه ی ?-استامیدو کتون ها با استفاده از تراکم چهار جزیی یک آلدهید آروماتیک، استوفنون، استیل کلرید و استونیتریل در دمای اتاق به کار رفت. sio2-ce(so4)2 بدون کاهش موثر در فعالیت کاتالیستی قابل بازیافت و استفاده ی مجدد می باشد. در این روش ?-استامیدو...
Catalytic hydrogenation of aromatic compounds is an important reaction which is useful for making key intermediates in organic chemistry and for the production of aromaticcontent-free fuels. More recently, there has been much interest in the potential for storage of molecular hydrogen, as an energy source, by catalytic hydrogenation of carboneous materials (e.g., fullerene and carbon nanotubes)...
Several 2-ketomethylquinolines were synthesized by heating, 2-methyl quinoline with acyl chloride in the presence of AlCl3 Contrary to reported procedures, this method was accomplished at a short time obtaining good results.
BACKGROUND The omega-3 polyunsaturated fatty acids (PUFA), docosahexaenoic acid (DHA) have well-characterized effects on inflammation and oxidative stress and may have neuroprotective effects in a number of neurodegenerative conditions including AD. Brain tissue contains large amounts of polyunsaturated fatty acids, which are particularly vulnerable to free radical injury. PURPOSE The present...
In order to study the effect of inorganic salt additives on surface tension a sodium dodecylbenzene sulfonate (SDBS) solution, mixed system six common additives, NaCl, CaCl2, AlCl3, Na2SO4, Na2CO3, and NaHCO3, SDBS was measured, effects types, surfactant concentrations solution were studied. On this basis, three salts, CaCl2 selected, their critical micelle concentration (CMC) The experimental ...
A purification procedure for C60 from the fullerene extract has been developed using the differential complexation of C60 and C70 with AlCl3 (or its conjugate acid) in CS2 solution. In addition to pure C60 (>99.8%), the procedure also provides C70-enriched fullerene mixture.
The first example of 1,2,4,3-triazaborole-based oxoborane has been synthesized via hydrogen migration upon the coordination of AlCl3 to the corresponding borinic acid. X-ray diffraction analysis and computational study disclosed the partial B[double bond, length as m-dash]O double-bond property.
Transition metal-mediated N-O bond cleavage reactions of heterobicycloalkene-fused 3-methyl-2-isoxazolines were investigated. Optimal cleavage conditions were found with Raney nickel/AlCl3 mediation in aqueous methanol. The reaction provided a diverse collection of novel heterobicycle-fused β-hydroxyketones with good to excellent yields (66-95%) and without the need for chromatographic purifica...
Herein the first inorganic magnesium salt solution capable of highly reversible magnesium electrodeposition is presented. Synthesized by acid-base reaction of MgCl2 and Lewis acidic compounds such as AlCl3, this salt class demonstrates upwards of 99% Coulombic efficiency, deposition overpotential of <200 mV, and anodic stability of 3.1 V.
