Single‐Step Synthesis of a Heterometallic [Cu2PdL4]2+ Hybrid Metal–Organic Coordination Cage

Angewandte Chemie, EarlyView.
A heterotrimetallic [Cu2PdL4]2+ lantern‐type cage has been synthesized in a single self‐assembly step from a low‐symmetry heterotopic ligand containing terminal groups with different metal coordination preferences, hybridizing the metallosupramolecular motifs of Cu4L4 and Pd2L4 cages.

Stable Mg2+ Dication Weakly Stabilized/Coordinated in Solution: Synthesis, Structure, Reactivity, and Use in Catalysis

Angewandte Chemie, EarlyView.
Stable Mg2+ dication stabilized only by weakly coordinating carborates was first prepared and structurally characterized as a soluble salt in organic solvents. Combined experimental and theoretical data provided valuable insights into its behavior/reactivity in solution.

Iridium‐Catalyzed Asymmetric Allenylic Substitution via Kinetic Resolution Enabled by New Monodentate Ligands

Angewandte Chemie, EarlyView.
The first kinetic resolution of allenylic alcohols by asymmetric allenylic substitution has been achieved, which was enabled by the design of a new chiral ligand that altered the energetic profiles of the previously established pathways. Both secondary and tertiary alcohols were suitable substrates.

Unprecedented “off‐pathway” [2+2] Cycloaddition‐Retroelectrocyclization Reaction Between an Unsymmetric Alkyne and Tetracyanoquinodimethane

Angewandte Chemie, EarlyView.
The widely used [2+2] cycloaddition‐retroelectrocyclization reaction between tetracyanoquinodimethane (TCNQ) and an activated alkyne has been shown to occur with “inverted” regiochemistry to give exclusive formation of an unexpected regioisomer. A combined experimental and theoretical study helped unravel the peculiar reaction mechanism underlying the ...

The Mechanism of Ruthenium‐Catalyzed Directed C─H Arylation of Arenes: The Key Role of Bis‐Cyclometalated Intermediates

Angewandte Chemie, EarlyView.
The mechanism of Ru‐catalyzed N‐directed C─H ortho‐arylation with haloarenes is addressed through experimental stoichiometric, catalytic kinetic, and DFT studies. These reveal a key role for bis‐cyclometallated ruthenium species and show bromoarene activation proceeds via a concerted oxidative addition.
