Electrochemical oxidation-induced etherification via C(sp3)─H/O─H cross-coupling [PDF]

open access: goldScience Advances, 2020
An electrochemical oxidation-induced C(sp3)─H etherification strategy by using nonsolvent alcohols has been disclosed. Direct electrochemical construction of C─O bonds through C(sp3)─H functionalization still remains fundamentally challenging.

Reaction Mechanisms Applied to Starch Modification for Biodegradable Plastics: Etherification and Esterification

open access: yesInternational Journal of Polymer Science, 2022
Although many studies are being actively conducted to develop biodegradable plastic materials, most of these reports focused more on efficiency or performance improvement than on the reaction mechanism. This paper discussed the reaction mechanism applied

Nucleophilic C-H Etherification of Heteroarenes Enabled by Base-Catalyzed Halogen Transfer.

open access: greenJournal of the American Chemical Society, 2021
We report a general protocol for the direct C-H etherification of N-heteroarenes. Potassium tert-butoxide catalyzes halogen transfer from 2-halothiophenes to N-heteroarenes to form N-heteroaryl halide intermediates that undergo tandem base-promoted ...

Microwave-Assisted Glycerol Etherification Over Sulfonic Acid Catalysts [PDF]

open access: goldMaterials, 2020
Glycerol is the main by-product of biodiesel production. For this reason, its valorization into value-added products, by using green procedures, represents an important goal.

Pd-Catalyzed Etherification of Nitroarenes [PDF]

open access: yesOrganometallics, 2021
The Pd-catalyzed etherification of nitroarenes with arenols has been achieved using a new rationally designed ligand. Mechanistic insights were used to design the ligand so that both the oxidative addition and reductive elimination steps of a plausible catalytic cycle were facilitated.

Etherification of Glycerol with Propylene or 1-Butene for Fuel Additives [PDF]

open access: goldThe Scientific World Journal, 2017
The etherification of glycerol with propylene over acidic heterogeneous catalysts, Amberlyst-15, S100, and S200 resins, produced mono-propyl glycerol ethers (MPGEs), 1,3-di- and 1,2-di-propyl glycerol ethers (DPGEs), and tri-propyl glycerol ether (TPGE).

Taking electrodecarboxylative etherification beyond Hofer–Moest using a radical C–O coupling strategy

open access: yesNature Communications, 2020
Since its discovery, the Hofer-Moest mechanism strongly limits the scope of electrochemical decarboxylative etherification. Here, the authors report the electrochemical conversion of carboxylic acids into alkyl benzotriazole ethers expanding the scope to

An Overview of the Production of Oxygenated Fuel Additives by Glycerol Etherification, Either with Isobutene or tert-Butyl Alcohol, over Heterogeneous Catalysts

open access: yesEnergies, 2019
Biodiesel production has considerably increased in recent decades, generating a surplus of crude glycerol, which is the main drawback for the economy of the process.

Promoting Effect of Ball Milling on the Functionalization and Catalytic Performance of Carbon Nanotubes in Glycerol Etherification [PDF]

open access: yesMolecules
A facile and eco-friendly approach using in situ-generated 4-benzenediazonium sulfonate (BDS) was applied to prepare highly functionalized carbon nanotubes (CNTs). The effectiveness of this functionalization was additionally enhanced by a green and short-
