Anthraquinone-Based Specialized Metabolites from Rhizomes of Bulbine natalensis
, 2019 The rhizomes of Bulbine natalensis furnished six previously unreported anthraquinone derivatives (1–6), together with eight known specialized metabolites. Their structures were determined by interpretation of 1D and 2D NMR and HRESIMS data.

Angewandte Chemie, EarlyView.Introducing [Co(CN)6]3− defects into CoNi Prussian Blue analogues exposes square‐planar Ni–N4 active sites, leading to remarkable H2O2 selectivity during the electrochemical oxygen reduction reaction in alkaline media. ABSTRACT Decentralized electrosynthesis of hydrogen peroxide (H2O2) via the two‐electron oxygen reduction reaction (2e− ORR) offers a ...

Anthraquinones tautomerism: VII. Hydroxy-substituted anthraquinones
Russian Journal of Organic Chemistry, 2007 Tautomerism of β-mono-, β,β'-dihydroxyanthraquinones, and their anions was studied for the first time by quantum-chemical and correlation methods. 2-Hydroxyanthraquinone exists exclusively in 9,10-quinoid form, and its ionization involves a tautomeric transformation into 10-oxido-2,9- anthraquinone.

Angewandte Chemie, EarlyView.Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Angewandte Chemie, EarlyView.Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale
