A heterogeneous, inexpensive, and environmentally friendly graphene oxide catalytic system for the C-H bond arylation of benzene enables the formation of biaryl compounds in the presence of aryl iodides. The oxygen functional groups in these graphene oxide sheets and the addition of KOtBu are essential for the observed catalytic activity. Reactions with various model compounds and DFT calculati...

Kinetics of reversible oxygenation and carbon monoxide complex formation of the simple heme compounds pyrroheme-N-[3-(1-imidazolyl)propyl]amide and pyrroheme-3-(3-pyridyl)propyl ester have been measured in different solvent environments. The oxygen on and off rates and equilibria of these compounds can be made to closely match those of myoglobin, of hemoglobin alpha chains, or of the various st...

A new general methodology for the synthesis of various functionalized privileged oxygen heterocyclic scaffolds, viz. pyrones, coumarins, and benzannulated coumarins, is developed. The synthesis proceeds through carbanion-induced ring transformation of lactones with various methylene carbonyl compounds followed by DDQ-mediated unprecedented oxidative cleavage of oxaylidenes intermediates. Studie...

In a previous theoretical study [B. Grimm and T. Bredow, Oxygen Defect Formation Thermodynamics of CaMnO3: A Closer Look. Phys. Status Solidi B 2022, https://doi.org/10.1002/pssb.202200427], the structural, thermodynamic, electronic properties CaMnO 3 have been studied. The present increases range compounds to ternary perovskites in search for suitable anode materials high-temperature water ele...

Treatment of hydrogen peroxide with a polymer-supported hypervalent iodine compound, poly[4-diacetoxyiodo] styrene (PDAIS), generates singlet molecular oxygen (O2) . Singlet oxygen generation was proved by trapping with typical organic compounds such as conjugated dienes, aromatic dienes, and electron-rich alkene. When compared to monomer analogue, the use of PDAIS in peroxidation of substrates...

CLO2 is an inorganic compound composed of oxygen; chloride; potassium and gold. Compounds of oxygen and chloride are formed from two electronegative elements. This chemical property of CLO2 makes possible the release of nascent oxygen upon decomposition during its action as an anti-microbial agent. Certain aspects of the cellular immune system (specifically white blood cells) utilize other mech...

A series of 1,2,4-triazine derivatives Va (1-24) and Vb (1-24) were synthesized and evaluated for their anti-anxiety and anti-inflammatory activities. The structures of the synthesized compounds were confirmed on the basis of their spectral data. Many of the triazine compounds were found to possess good activity. Especially, compounds bearing the sulfur atom showed better activity than those be...
