Reação da cânfora com boroidreto de sódio: uma estratégia para o estudo da estereoquímica da reação de redução Reaction of camphor with sodium borohydride: a strategy to introduce the stereochemical issues of a reduction reaction

Química Nova, 2010
Reduction of camphor to a mixture of borneol and isoborneol was performed using NaBH4 as the reducing agent under suitable conditions. Although more effective reduction was accomplished using toxic methanol, an alternative non-toxic ethanolic system is ...

Quantification of Nε-(2-Furoylmethyl)-L-lysine (furosine), Nε-(Carboxymethyl)-L-lysine (CML), Nε-(Carboxyethyl)-L-lysine (CEL) and total lysine through stable isotope dilution assay and tandem mass spectrometry [PDF]

, 2015
The control of Maillard reaction (MR) is a key point to ensure processed foods quality. Due to the presence of a primary amino group on its side chain, lysine is particularly prone to chemical modifications with the formation of Amadori products (AP), Nε-

Alcohol deoxygenation in the presence of SiO2@FeSO4 nanocomposite

Results in Chemistry
SiO2@FeSO4 nanocomposite was studied as a nanocatalyst for deoxygenation of alcohols. Alcohols were converted to alkanes by removing oxygen in the presence of SiO2@FeSO4 nanocatalyst.

Rehydrogenation of Sodium Borates to Close the NaBH₄-H₂ Cycle: A Review

Energies, 2021
In 2007, the US Department of Energy recommended a no-go on NaBH4 hydrolysis for onboard applications; however, the concept of a NaBH4-H2-PEMFC system has the potential to become a primary source for on-demand power supply.
