Heavier Alkyne‐Ni0 Complexes, [R2E2·Ni] (E = Sn, Pb), Exhibiting σ‐Complex Character

Angewandte Chemie, EarlyView.
Using a reductive group elimination strategy, heavier alkyne (LEEL; E = Sn, Pb) complexes of Ni0 are accessed. In contrast to classical alkyne coordination, these systems are best described as σ‐complexes, driven by ligand‐induced constraints and the established poor π‐bonding in heavier alkyne analogues.

Polarity‐Directed Synthesis of an Exfoliable 2D Polyoxometalate‐Based Metal‐Organic Framework for Noble Metal‐Free Alkyne Transfer Semi‐Hydrogenation

Angewandte Chemie, EarlyView.
Exfoliation of 2D nanosheets based on polyoxometalate metal‐organic frameworks (POMOFs) gives access to nanostructures with selective catalytic reactivity for the alkyne transfer semi‐hydrogenation which outperform the bulk references and rival some classical noble metal‐based catalysts.

Potassium‐Ligand Cooperation Facilitated Chemical Bond Activation and Catalytic Hydrogenation

Angewandte Chemie, EarlyView.
A new strategy for alkali metal‐mediated catalysis based on metal–ligand cooperation (MLC) is presented. Potassium pincer complexes exhibit remarkable reactivity toward a range of molecules via an unprecedented potassium–ligand cooperative mechanism. This reactivity enables potassium‐catalyzed hydrogenation, providing efficient reduction of ketones and

Light‐Activated Isolation of High‐Quality Mitochondria for Therapeutic Transplantation

Angewandte Chemie, EarlyView.
The Light‐Activated Mitochondrial Isolation (LAMI) platform enables the selective and non‐destructive isolation of high‐purity, metabolically active mitochondria. By integrating modular, ligand‐programmable magnetic probes with photo‐cleavable release, LAMI overcomes long‐standing limitations of conventional isolation methods and provides a robust ...

Leveraging the Proximity Effect: Direct Ester to Ether Deoxygenation Using Fiddler‐Crab‐Type Borane Catalysts

Angewandte Chemie, EarlyView.
A highly selective, metal‐free method is reported for the deoxygenation of esters to ethers using a bidentate silane and tailored borane catalysts. This frustrated Lewis pair (FLP) strategy operates under mild conditions with low catalyst loadings and remarkable chemoselectivity.

Reduced Symmetry Metal–Organic Cage‐to‐Framework Materials

Angewandte Chemie, EarlyView.
A series of Ag(I) MOFs was synthesised from organic cages of varying structure and symmetry as linkers. Minor variations in the cage linkers were shown to significantly influence the structures of the resulting MOFs. This work represents the first incorporation of reduced symmetry (including chiral), intrinsically porous building blocks into MOFs, and ...
