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.

Asymmetrische α‐Alkylierung mit aktivierten und unaktivierten Elektrophilen durch einen hocheffizienten und rezyklierbaren Lewis‐Säure/Imidazolium‐Katalysator

Angewandte Chemie, EarlyView.
Ein luftstabiler, einfach herzustellender bifunktioneller Cu(II)/Imidazolium‐Komplex ermöglicht hoch enantioselektive α‐Alkylierungen von 1,3‐Dicarbonylverbindungen mit herausragender Produktivität (TON bis zu 1740). Zu den hervorzuhebenden Merkmalen zählen ein breites Elektrophilspektrum, das sowohl π‐aktivierte als auch nicht aktivierte Reagenzien ...

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 ...
