Electrooxidative Functionalizations of Dehydroabietic Acid [PDF]

Bulletin of the Chemical Society of Japan, 1987
Abstract Dehydroabietic acid methyl ester (1) was converted into 7-acetoxydehydroabietic acid methyl ester by direct electrooxidation in acetic acid and 7-oxodehydroabietic acid methyl ester by ruthenium dioxide-mediated oxidation. Non-Kolbe type electrodecarboxylation of 1 resulted in the introduction of a double bond into the ring A of

Reconstruction of Nickel Chalcogenide Induced Ruthenium Nanoparticles Embedding for Oxygen Evolution: Mechanism Switching Enables Enhanced Catalytic Activity

Advanced Science, EarlyView.
Ru nanoparticles supported nickel chalcogens (Ru/NiX, X = S, Se), which enable fast electrooxidation to form an adaptively Ru embedding structure, featured by the compressed Ru─O─Ni bridge bonds at the Ru/NiOOH interface. On the one hand, Ru nanoparticles have a high affinity for capturing the OH−, consequently increasing the *O radical coverage.
