Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water
European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.Background Enzymatic hydrolysis can enhance the flavor of food. The amino acids and peptides generated through enzymatic hydrolysis of poultry protein not only enhance protein absorption and utilization but also improve flavor. Methods This study utilized duck meat enzymatic hydrolysate as the primary additive for the preparation of duck meat sauce ...

A Mild Isomerization Reaction for β,γ-Unsaturated Ketone to α,β-Unsaturated Ketone
, 2013 A series of β,γ-unsaturated ketones were isomerized to their corresponding α,β-unsaturated ketones by the introduction of DABCO in iPrOH at room temperature. The endo-cyclic double bond (β,γ-position) on ketone was rearranged to exo-cyclic double bond (α,
