In this issue of Chem, Dong and colleagues show that an engineered mixed carboxylate carbonate anhydride serves as an electrophilic trap in palladium/norbornene-catalyzed double functionalization of aryl iodides, enabling the introduction of the synthetica ...
Unsymmetrical Zn phthalocyanine consisting of six S-aryl groups at alpha-positions and a carboxy anchoring group at beta-position has been designed and synthesized for dye-sensitized solar cells (DSCs) applications. The unsymmetrical phthalocyanine has bee ...
Phenolic compounds are known structural moieties of natural organic matter (NOM), and their reactivity is a key parameter for understanding the reactivity of NOM and the disinfection by-product formation during oxidative water treatment. In this study, spe ...
Reduction of CO2 by electrochemical and photoelectrochemical methods to produce carbon-rich fuels is a heavily pursued research theme. Most of the current efforts are focused on the development of transition-metal-based catalysts. In this tutorial review, ...
In this study visible light active iodine doped titanium dioxide samples prepared by sol-gel method were investigated. Photocatalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray fluorescence spectroscopy (XF ...
Background: The quantification of total (free + sulfated) metanephrines in urine is recommended to diagnose pheochromocytoma. Urinary metanephrines include metanephrine itself, normetanephrine and methoxytyramine, mainly in the form of sulfate conjugates ( ...
Dissolved Organic Matter (DOM) is a complex mixture of thousands of organic molecules ubiquitously present in surface waters. Its influence on the photodegradation of organic contaminants is a complicated topic. For decades DOM had been mostly assumed to h ...
An efficient one-step synthesis of piperidin-2-yl and pyrrolidin-2-yl flavonoid alkaloids was achieved in good to excellent yields by a highly regioselective phenolic Mannich reaction of chrysin with cyclic imines or iminium salts. Performing the reaction ...
The reactivity of phenolic compounds can be drastically affected by the electronic nature of the substituting groups. In this work, the effect of physico-chemical properties on the reactivity via photo-assisted Fenton catalysis is reported for several para ...
The first enantioselective chiral phosphoric acid-catalyzed transfer hydrogenation of N-aryl-ortho-hydroxybenzophenone ketimines using a Hantzsch ester as hydrogen source was developed to afford, after removal of the N-aryl group, the corresponding chiral ...
