Nucleophilic Gallyl Anions Enable Ga─Au Bimetallic Ammonia Activation

Angewandte Chemie, EarlyView.
Unlocking gallyl nucleophiles: Counterion control enables formation of an unsupported gallyl─gold complex. Gold coordination induces a polarity switch at gallium, enabling cooperative activation of NH3 and related N─H/O─H substrates under mild conditions.

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

Coordination‐Driven Direct C─H Metalation of N‐Heterocycles With a Superbasic Co(II) Amide Co(TMP)2

Angewandte Chemie, EarlyView.
By enabling regioselectivities that are inaccessible with conventional bases, this study introduces a Co(II) amide platform for the deprotonative C─H metalation of sensitive N‐heterocycles. Subsequent interception of the resulting Co(II) intermediates with external oxidants affords a family of sterically congested, TMP‐substituted heterocycles via C─N ...

An Enantioselective Alkene Aminoarylation to Form Chiral Indolines via Electrostatically‐Directed Palladium Catalysis

Angewandte Chemie, EarlyView.
Enantioselective aminoarylation of ortho‐allyl anilines is achieved under mild conditions. Key to success is the electrostatically‐directed nature of the key aminopalladation step, achieved by using the sulfonated chiral ligand sSPhos on palladium. A detailed study of electronic trends allows tuning of the sulfonamide protecting group to enable good ...
