Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...

Plant Biology, Volume 28, Issue 6, Page 1796-1812, October 2026.Two factors identified by co‐expression analysis of photosynthetic regulators are described, which are involved in thylakoid pigment content and composition and, through their function, shape the dynamics of NPQ. Abstract Rapid fluctuations in light intensity require swift regulatory adjustments of photosynthesis. Although the major plant regulators of

Catalytic Sulfur‐Atom Transfer Enabled by a Bis(disulfide) Titanium Complex
Angewandte Chemie International Edition, Volume 65, Issue 39, 21 September 2026.Multi‐electron transformations with titanium are underexplored due to limited access to low‐valent precursors. The four‐electron activation of elemental sulfur by a Ti(IV) complex yields a rare titanium bis(disulfide) complex, enabling the efficient catalytic synthesis of isothiocyanates from isonitriles under mild conditions.

Stereochemistry of Epoxidation of Some Caryophyllenols
, 2016 Epoxidation of the caryophyllene allylic alcohols 3−5 by tert-butyl hydroperoxide/vanadyl acetylacetonate afforded the epoxides 6a, 7, and 8, respectively. The tetracyanoethylene-catalyzed solvolysis shed some light on the stereochemistry of epoxidation.
