European Journal of Inorganic Chemistry, EarlyView.The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...

European Journal of Inorganic Chemistry, EarlyView.The first low‐oxidation (I/III) state chromium‐complex bearing a O‐chelating NHC ligand has been synthesized and structurally characterized by single‐crystal X‐ray analysis. The formation of the mixed‐valence species was further supported by SQUID magnetometry and high‐field electron paramagnetic resonance (EPR) spectroscopy.

Emerging Trends in Organic Photoreactions Utilizing Disulfides
European Journal of Organic Chemistry, EarlyView.Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...

A quick review of carbamazepine pharmacokinetics in epilepsy from 1953 to 2012
Journal of Research in Medical Sciences, 2013 Background: Carbamazepine has been used as AEDs since 1965, and is most effective against partial seizures. Two basic mechanisms of action have been proposed: 1) enhancement of sodium channel inactivation by reducing high-frequency repetitive firing of ...

European Journal of Organic Chemistry, EarlyView.A simple bifunctional organocatalyst derived from the FDA‐approved chelator deferiprone efficiently promotes CO2 fixation into cyclic carbonates. By combining epoxide activation and nucleophilic ring opening in a single scaffold, quantitative conversions are achieved under mild, metal‐free conditions. High activity, broad substrate scope, and excellent

Oxygen Attachment Dissociation of Protonated Reserpine and Its Analogs. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Carbon–carbon double bonds are ubiquitous structural motifs in natural products and pose a key challenge in locating their presence in analytes via MS‐based methods. Here, we use the alkaloid reserpine as a model system to examine whether OAD reactions can locate quaternary double bonds embedded in fused multicyclic structures ...
