Tungstophosphoric Acid Supported on Silica-encapsulated γ-Fe2O3 Nanoparticles Catalyzed Oxidative Amidation
We have used tungestophosphoric acid to catalyze oxidative amidation reaction from benzyl alcohols and methylarens with hydrochloride salts of amines. To achieve this purpose, modified magnetic nanoparticles (γ-Fe2O3@SiO2@H3PW12O40) were applied as catalyst and TBHP as external oxidant. After optimizing, different derivates of be...
متن کاملVanadium Oxide Supported on Al-modified Titania Nanotubes for Oxidative Dehydrogenation of Propane
In this study, characterization of vanadia supported on Al-modified titania nanotubes (TiNTs) synthesized by the alkaline hydrothermal treatment of TiO2 powders has been reported. A promising catalyst for oxidative dehydrogenation (ODH) of propane was prepared via the incipient wetness impregnation method. The morphology and crystalline structure of TiNTs were characterized by transmission elec...
متن کاملDirect synthesis of hydrogen peroxide on palladium catalyst supported on sulfonic acid-functionalized silica
Recently, H2O2 is drawing growing interest in green chemistry 15 because it acts as direct and environmental benign oxidant in organic synthesis [2] and because its high cost limits the use for the production of bulk organic chemicals. The synthesis of hydrogen peroxide by direct reaction between H2 and O2 is a very attractive alternative to traditional anthraquinone 20 process. Direct synthesi...
متن کاملLewis acid-assisted formic acid dehydrogenation using a pincer-supported iron catalyst.
Formic acid (FA) is an attractive compound for H2 storage. Currently, the most active catalysts for FA dehydrogenation use precious metals. Here, we report a homogeneous iron catalyst that, when used with a Lewis acid (LA) co-catalyst, gives approximately 1,000,000 turnovers for FA dehydrogenation. To date, this is the highest turnover number reported for a first-row transition metal catalyst. ...
