Site-selective Electrochemical Oxidation of Glucosides [PDF]

open access: yesACS Catalysis, 2022
Quinuclidine-mediated electrochemical oxidation of glycopyranosides provides C3-ketosaccharides with excellent selectivity. The method is a versatile alternative to Pd-catalyzed oxidation, and to photochemical oxidation, and is complementary to the TEMPO-mediated C6-selective oxidation. Contrary to the electrochemical oxidation of methylene and methine

Selective oxidation of methane to methanol over Au/H-MOR [PDF]

open access: yes, 2023
Selective oxidation of methane to methanol by molecular oxygen is a fascinating route for upgrading abundant methane resource and represents one of the most challenging reactions in chemistry due to the overwhelmingly higher reactivity of the product ...

Selective Enzymatic Oxidation of Silanes to Silanols [PDF]

open access: yes, 2020
Compared to the biological world’s rich chemistry for functionalizing carbon, enzymatic transformations of the heavier homologue silicon are rare. We report that a wild-type cytochrome P450 monooxygenase (P450BM3 from Bacillus megaterium, CYP102A1) has ...

Real-time quantitative analysis of volatile products generated during solid-state polypropylene thermal oxidation [PDF]

open access: yes, 2013
Analysis of volatile organic compounds (VOCs) during PP thermal oxidation under three oxygen partial pressures (0%, 21% and 100% of atmospheric pressure) at 140 C was performed by proton transfer reaction coupled with Fourier transform ion cyclotron ...

Selective aerobic oxidation of 1,3-propanediol to 3-hydroxypropanoic acid using hydrotalcite supported bimetallic gold nanoparticle catalyst in water [PDF]

open access: yes, 2015
Selective oxidation of 1,3-propanediol (1,3-PD) to 3-hydroxypropanoic acid (3-HPA), an important industrialbuilding block, was successfully achieved using hydrotalcite-supported bimetallic Au nanoparticle catalysts in water at 343 K under aerobic and ...

Catalysts for the Selective Oxidation of Methanol [PDF]

open access: yesCatalysts, 2016
In industry, one of the main catalysts typically employed for the selective oxidation of methanol to formaldehyde is a multi-component oxide containing both bulk Fe2(MoO4)3 and excess MoO3. It is thought that the excess MoO3 primarily acts to replace any molybdenum lost through sublimation at elevated temperatures, therefore preventing the formation of

Alkyl ferulic acid esters: Evaluating their structure and antibacterial properties

open access: yesFrontiers in Microbiology, 2023
Ferulic acid (FA) is a natural antibacterial agent rich in plants, FA has excellent antioxidant and antibacterial properties. However, because of its short alkane chain and large polarity, FA is difficult to penetrate the soluble lipid bilayer in the ...
