Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5563-5579, August 2026.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Direct NMR Evidence of Distinct Cation‐CO2 Adducts in Asymmetric Phosphonium‐Based Aprotic N‐Heterocyclic Anion (AHA) Ionic Liquids

open access: yesChemSusChem, Volume 19, Issue 14, 29 July 2026.
An in situ NMR method using isotopically enriched 13CO2 reveals regioisomeric cation‐CO2 adducts in asymmetric phosphonium‐based aprotic N‐heterocyclic anion ionic liquids. Two distinct carboxylate species, formed at chemically nonequivalent α‐carbons, are unambiguously identified and quantified.

Catalytic Enantioselective Multicomponent Reactions of Sulfoxonium Ylides Enabled by a Formal Rearrangement—A Versatile Entry to Enantioenriched α‐Sulfanyl Carbonyl Compounds

open access: yesAngewandte Chemie, Volume 138, Issue 28, 6 July 2026.
A catalytic network embedding a formal rearrangement enables the first catalytic enantioselective multicomponent reaction (MCR) of sulfur ylides. In the presence of a bulky chiral phosphoric acid, the reaction combines sulfoxonium ylides, aldehydes and thiols, and affords synthetically versatile β‐hydroxy‐α‐sulfanyl carbonyl compounds in ...

Dinuclear Copper(I) Complexes Featuring Metal–Metal Interactions and a μ2‐Bridging Phosphane With Additional Olefinic Binding Sites

open access: yesChemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
A Cu2P triangle captured in a tetrapodal phosphane tris(olefin) ligand, where all binding forces are weak apart from the Cu─P interaction. ABSTRACT The molecule Ptrop3 contains in each trop unit (trop = dibenzo[a,d]cyclohepten‐5‐yl) a rigid central seven‐membered ring with an olefinic binding site making Ptrop3 potentially a tetradentate ligand ...

Properties of [Fe(salen)]2‐μ‐Oxo Derivatives and Their Effect on Catalytic Hydrophosphination

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 26, 13 July 2026.
A series of [Fe(salen)]2‐μ‐oxo and [Fe(salophen)]2‐μ‐oxo complexes were synthesized to probe how ligand electronics and backbone rigidity influence redox behavior and catalytic hydrophosphination of styrene. Electron‐withdrawing substituents enhance stability and activity, enabling tunable, efficient C–P bond formation.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.
