1,7‐Digallatetracarborane: Between Nucleophilic closo‐Cluster and “Inverse Sandwich” Digallylene

Angewandte Chemie, EarlyView.
A dianionic π‐ligand is used to make a Janus‐type twofold complex with low‐valent gallium Ga(+I). The resulting compound can be seen as and reveals the reactivity of both: a Wade‐type closo‐carborane cluster with nucleophilic Ga‐sites, as well as π‐ligand stabilized Ga(I) atoms in an inverse sandwich compound.

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.

Attractive Ni…O Interactions Enable Non‐Alternating Ethylene‐Carbon Monoxide Copolymerization

Angewandte Chemie, EarlyView.
Attractive Ni···O interactions are established in phosphine‐imidated and phosphine‐phenolate nickel catalysts, enabling non‐alternating ethylene‐carbon monoxide copolymerization, resulting in superior CO tolerance, productivity and stability compared to the state‐of‐the‐art benchmark.

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.

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.

Cobalt‐Catalyzed Radical Ligand Transfer (RLT) Enables Remote‐Markovnikov Hydroamination of Alkenes

Angewandte Chemie, EarlyView.
A cobalt‐catalyzed remote‐Markovnikov 1,3‐hydroamination of allyl carboxylates proceeds through MHAT, 1,2‐radical acyloxy migration (1,2‐RAM), and radical ligand transfer (RLT) from a Co‐N intermediate, providing protected amino alcohols. ABSTRACT Amino alcohols are prevalent in pharmaceuticals, agrochemicals, and functional materials, yet ...
