In this paper, the dehydrogenation reaction of NaBH4 was performed in presence Co-ion loaded hydrogel catalyst. The reactions took place within 27, 18 and 9 hours at 25, 35 45 °C, respectively. addition, relation between initial concentration released hydrogen investigated 45°C. A linear relationship borohydride produced H2 determined. Also, differential method used to determine rate constants ...

NaBH4 is a very cheap and hydrogen-rich material, as well potential hydrogen store. However, the high temperature of its thermal decomposition (above 530 °C) renders it inapplicable in practical use. Here, we studied effect addition diverse V-containing catalysts on desorption. It turns out that mechanochemical doping with vanadium metal, oxides, or nanoparticles lowers pyrolysis significantly....

Functionalized 3-trifluoromethyl-2-isoxazolines and 3-trifluoromethylisoxazoles were easily prepared from trifluoromethyl aldoxime 2 under mild conditions by using DIB as oxidant. Theoretical studies of the reactivity of trifluoroacetonitrile oxide 4 toward olefins and alkynes were carried out. The 3-trifluoromethyl-2-isoxazolines were ring-opened with NaBH4 and NiCl2 to yield the corresponding...

Metal tellurolates (M = B3+; BuTeTeBu/NaBH4/EtOH; Li3+, Te0/BuLi/THF; In3+, BuTeTeBu/InI/EtOH) react with aminoalkynes to produce vinylic tellurides containing amino groups; the regio-, and stereo-chemistry of the hydrotelluration reaction depend on the metallic counter ion and on the nature of the amino group substituent.

Addition of functionalized aryl, heteroaryl or adamantyl zinc reagents to various nitroso-arenes in the presence of magnesium salts and LiCl in THF produces after a reductive work-up with FeCl2 and NaBH4 in ethanol the corresponding polyfunctional secondary amines in high yields.

Fe(BF4)2·6H2O/2,6-pyridinedicarboxylic acid catalysed nitrosation of a wide variety of substituted styrenes has been developed in the presence of t-BuONO/NaBH4 under H2 pressure (10 bar) in MeOH-H2O (5 : 1) to afford corresponding oximes in good to excellent yields.

We present a straightforward, environmentally-benign, one-pot photochemical route to generate alloyed AgAu bimetallic nanoparticle decorated aminoclays in water at room temperature. The protocol uses no reducing agent (e.g., NaBH4) nor is photocatalyst required. These hybrid materials show excellent promise as dual catalysts/antibacterial agents.
