Breaking the Mold: Electrophilic Hydrophosphanation Emerges

Chemistry – A European Journal, EarlyView.
Electrophilic hydride attack on the olefin, instead of the classical nucleophilic addition by a phosphanido ligand, is unveiled in rhodium‐catalyzed olefin hydrophosphanation. This hydride‐driven pathway operates for both activated and inactivated olefins, with transition states characterized by elongated Rh─H bonds and nascent C─H bond formation ...

Flipping the Card With Enantiodivergent Organocatalysis

Chemistry – A European Journal, EarlyView.
This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...

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

European Journal of Organic Chemistry, EarlyView.
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.

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Sustainable Utilization and Fire Protection of Wood‐Based Composites in Buildings: Innovations, Challenges, and Future Directions

Sustainable Development, EarlyView.
ABSTRACT The increasing use of wood and wood‐based composites in construction reflects a global shift toward renewable materials that support sustainable development objectives, including carbon reduction and responsible resource use. While wood offers substantial environmental benefits compared to conventional materials such as concrete and steel, its

Surface Engineering of Ti3C2Tx MXenes via Silanol Functionalization for Improved Electrochemical Performance

Small, EarlyView.
This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.

Strain‐Mediated Anisotropic Growth of Metal–Organic Framework Belts

Small Methods, EarlyView.
An aqueous, one‐pot synthesis redirects layered ZIF‐L from conventional leaf morphology to high–aspect‐ratio belts (∼ 10) by pH‐controlled anisotropic growth, with magnetic nanoparticles decorating the platelet surfaces (MZIF‐L), improving phase stability during post‐synthetic handling.

The Underlying Chemistry to Formation of Phosphoryl Radicals from Organophosphorus Compounds - A Missing Puzzle Piece in the Flame Chemistry.

Chemistry, 2020
Reactive species such as ∙PO 2 and HOPO are considered of upmost importance in flame inhibition and catalytic combustion processes of fuels. However, the underlying chemistry of their formation remains speculative due to the unavailability of suitable ...

The Generics Revolution and the New Economic Geography of the Global Pesticide Industry

Journal of Agrarian Change, EarlyView.
ABSTRACT The global pesticide industry transformed from one dominated by patented products and legacy multinationals with strong manufacturing bases in the United States and EU to one dominated by generic products produced in India and China. We use proprietary market research data, data from regulatory filings, industry press and bilateral trade data ...
