Ligand architecture and secondary‐sphere effects in a well‐defined cobalt(IV)–oxo complex

Bulletin of the Korean Chemical Society, EarlyView.
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 ...

Glutaraldehyde-crosslinked Rhizopus oryzae whole cells show improved catalytic performance in alkene epoxidation

Microbial Cell Factories, 2023
Background Existing methods for alkene epoxidation are based on lipase-catalysed perhydrolysis. However, the inactivation of the expensive lipase enzyme is problematic for enzymatic epoxidation at large scales due to the use of hydrogen peroxide and ...

Simultaneous Photoactivation of Copper and Ti‐Doped CeO2−x Enables Optimal Acceleration of the RWGS Reaction

Carbon Energy, EarlyView.
A combination of visible light and thermal energy accelerates the CO formation rate up to 57 times compared to dark conditions using a 3Cu/CeTiO2−x catalyst. Kinetic analysis, as well as steady state and transient spectroscopy, was applied under photocatalytic conditions to analyze and disentangle the reaction channels under dark and illuminated ...

Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

European Journal of Inorganic Chemistry, EarlyView.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...
