Ligand architecture and secondary‐sphere effects in a well‐defined cobalt(IV)–oxo complex
Bulletin of the Korean Chemical Society, Volume 47, Issue 4, Page 484-492, April 2026.A well‐defined cobalt(IV)–oxo complex supported by a neutral tetraazamacrocyclic ligand is generated and fully characterized. The cobalt(IV)–oxo species exhibits electrophilic oxygen‐atom and hydrogen‐atom transfer reactivity, strongly modulated by protonation and secondary coordination sphere effects, providing new insight into structure–reactivity ...

The role of pressure anisotropy in the turbulent intracluster medium
, 2012 In low-density plasma environments, such as the intracluster medium (ICM), the Larmour frequency is much larger than the ion-ion collision frequency. In such a case, the thermal pressure becomes anisotropic with respect to the magnetic field orientation ...

Relationship between electrophilicity index, Hammett constant and nucleus-independent chemical shift
Journal of Chemical Sciences, 2005 Inter-relationships between the electrophilicity index (Ω), Hammett constant (op@#@) and nucleusindependent chemical shift (NICS (1) — NICS value one angstrom above the ring centre) have been investigated for a series of meta- and para-substituted benzoic acids. Good linear relationships between Hammett constant vs electrophilicity and Hammett constant

Equilibrium constants and protonation site for N-methylbenzenesulfonamides
Beilstein Journal of Organic Chemistry, 2011 The protonation equilibria of four substituted N-methylbenzenesulfonamides, X-MBS: X = 4-MeO (3a), 4-Me (3b), 4-Cl (3c) and 4-NO2 (3d), in aqueous sulfuric acid were studied at 25 °C by UV–vis spectroscopy.

Picolinic acid promoted oxidative decarboxylation of phenylsulfinylacetic acid by Cr(VI)
Bulletin of the Chemical Society of Ethiopia, 2016 The kinetics and mechanism of picolinic acid promoted reaction of phenylsulfinylacetic acid (PSAA) with Cr(VI) was carried out in aqueous acetonitrile medium under pseudo first order conditions. The reaction follows Michaelis-Menten type of kinetics with
