Correlation Between the Molecular Structure of Metal‐Supporting Ligands and Catalysis in the Oxygenase‐Mimicking Immobilized Metal Complex Catalysts

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 ...

1,2‐Diazetidines − Structure, Synthesis, and Functionalization

European Journal of Organic Chemistry, EarlyView.
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

Fractionation of Milligram Quantities of Gadolinium and Terbium Ions by Annular Free‐Flow Isotachophoresis

ELECTROPHORESIS, EarlyView.
ABSTRACT The fractionation of milligram quantities of gadolinium (Gd) and terbium (Tb) ions is demonstrated using annular free‐flow isotachophoresis (ITP) with ammonium as the leading ion and hydronium as the terminating ion, and α‐hydroxyisobutyric acid (HIBA) and acetate as lanthanide complexing ligands.
