Post‐Synthetic Zinc Modifications to Correct Speciation in Ti‐MWW Zeolites for Catalytic Oxidation
Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.Post‐synthetic Zn modifications of Ti‐MWW zeolite catalysts exhibit improved catalytic properties in the selective oxidation reaction, namely the ammoximation reaction. The origin of the beneficial effect of Zn is related via an array of spectroscopic and microscopic techniques to the modification of extra‐framework TiO2 and TiOx clusters and the ...

Development of a catalyst for epoxidation of methyl esters
, 2022 The diploma thesis is focused on the study of heterogeneous catalysts in the epoxidation of rapeseed oil methyl ester. Epoxides of these components have applications in cutting oils, where they could replace hitherto used oils from fossil sources ...

π‐Extended Salphen Scaffolds Enable CO2 Electroreduction and Singlet Oxygen Generation
Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.New family of π‐extended salen ligands bearing phenylene bridge and tunable phenyl‐based substituents, and their corresponding boron difluoride complexes. Thanks to the extended π‐delocalization over the molecule, the ligands themselves show promising results in electrochemical CO2 reduction to CO, while the complexes act as efficient photosensitizers ...

Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex
Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.

Amide‐Enabled Reversal of Regioselectivity in Carbonyl‐Substituted Allenes
Advanced Synthesis &Catalysis, Volume 368, Issue 20, 16 October 2026.A substrate‐embedded secondary amide reverses the inherent regioselectivity of carbonyl‐substituted allenes, enabling rhodium‐catalyzed α‐acyloxylation with carboxylic acids. This redox‐neutral method requires no external oxidants or auxiliary‐type directing groups and tolerates diverse carboxylic acids.

Synthesis and Polymerization of a Lactone Building Block Derived From Cashew Nut Shells
ChemSusChem, Volume 19, Issue 19, 14 October 2026.Cardanol as a renewable substituted phenol feedstock was selectively transformed into the corresponding cyclohexanone derivative by means of a partial metal‐catalyzed hydrogenation. Subsequent conversion via Baeyer–Villiger oxidation gave a lactone product consisting of a mixture of regioisomers, which has been readily converted into its homopolymer ...
