Effect of Water on Electrochemical β‐Hydrocarboxylation of Vinylphenol Derivatives With CO2
Asian Journal of Organic Chemistry, Volume 15, Issue 2, February 2026.Electrochemical hydrocarboxylation of vinylphenols with CO2 was accomplished under mild conditions in an undivided cell without the use of a sacrificial anode. Optimal conditions using tetraethylammonium p‐toluenesulfonate (Et4NOTs), water, and a low current density enabled the efficient synthesis of carboxylic acids from vinylphenol derivatives in the

Oxidative depolymerisation of kraft lignin
, 2023 The production of green hydrogen may be greatly aided by the use of an alternative anode reaction replacing oxygen evolution to increase energy efficiency and concomitantly generate value-added products. Lignin, a major component of plant matter, is accumulated in large amounts in the pulp and paper industry as waste.

Depolymerisation of γ‐Valerolactone Organosolv Lignins with Unsupported Molybdenum‐Based Catalysts
ChemSusChem, Volume 19, Issue 3, February 2026.Lignins from γ‐valerolactone organosolv fractionation were depolymerised in ethanol using unsupported molybdenum catalysts. Over 90% yields of low‐molecular‐weight lignin oil were obtained with minimal char formation, yields of the aromatic monomers being 7–16 wt%.

ChemSusChem, Volume 19, Issue 3, February 2026.Sulfoethylated and carboxyethylated lignin derivatives were fabricated, and their impacts on stabilizing soybean oil–water were analyzed in Pickering and non‐Pickering systems. It was noticed that the lignin derivatives behaved very differently, implying that the modification routes played an important role in their performance.
