LA Highbarger,JA Gerlt,GL Kenyon - 《Biochemistry》 被引量: 241发表: 1996年 Development of silver nanoparticle loaded antibacterial polymer mesh using plasma polymerization process Plasma polymerized polyacrylic acid (PPAA) was deposited on a polymer substrate, namely polyethylene terephthalate (PET) me...
57、f amines, oximes 59 and ni- trogen containing heterocycles 2. (53) The NaBH(OAc)3reagent has been used for the chemoselective reduction of aldehydes in the presence of ketones 2. Also, selective reduction of ketones using NaBH4in glacial acetic acid solvent or NaBH4in THF using 3 equiv...
Various materials with different acid/base surface properties have been chosen as supports (hydrotalcites, KF/Al2O3, heteropolyanions). The supports and the Co-containing catalysts were characterized by X-ray diffraction, scanning electron microscopy with energy-dispersive X-ray spectroscopy, X-ray ...
In the combustion method, a metallic precursor acts as an oxidizer (normally metal nitrate) that reacts with an organic fuel as a reduc- ing agent (such as sugar, amino acid, urea, ethylene urea, glycine, cetyltrimethylammonium bromide (CTAB), etc.) below a specified degree of combustion ...
The epoxides are easily obtained in up to 95% ee through routine acid–base workup of the product alcohols. Either the ( R) or ( S) epoxide can be obtained by using the appropriate l- or d-tartaric acid starting material in the TarB-NO 2 reagent....
The initiator system used generally comprises a Lewis acid and an “inifer”, i.e. an organic compound having an easily displaceable leaving group which forms a carbocation or a cationic complex with the Lewis acid. The inifer is generally a tertiary halide, a tertiary ester or ether or a...
[62]) is in great need for the recycling of the hydrogen supply system of NaBH4: NaBH4 + xH2O → H2 + NaBO2·xH2O, (x = 2, 4) (1) According to this, the Brown-Schlesinger process was modified using NaBO2 as source of boric acid to synthesis of NaBH4 [63], the drawback of ...
Decades ago, the Wolfrom method [1] was reported, which employs hydriodic acid as the reducing agent and then a protocol involving catalytic amounts of diethyl peroxydicarbonate in isopropanol [2]. The interesting transformation of α-diazo-β-hydroxy esters into β-keto esters [3,4] catalyzed ...
The product spots were visualized with a solution of phosphomolybdic acid (PMA), p-anisaldehyde, iodine (I2), or cerium ammonium molybdate (CAM). Preparative TLC (pTLC) was performed on Merck PLC Silica gel 60 F254, 0.5 mm. Flash silica-gel column chromatography (SiO2-chromatography) ...
