NiH‐Catalyzed Enantioconvergent α‐Alkenylation of Carbonyl Compounds via Markovnikov Alkyne Hydronickellation

Angewandte Chemie, EarlyView.
A NiH‐catalyzed α‐alkenylation via Markovnikov hydronickellation of alkynes enables convenient access to α‐chrial β‐methylene carbonyl frameworks that are prevalent in biorelevant molecules. High regio‐ and enantioselectivities have been achieved with excellent functional group tolerance and applicability toward complex structures. The β‐methylene unit

Sequential Homo‐ and Hetero‐Coupling of Isocyanide and Carbon Monoxide Mediated by Acyclic Imino(silyl)Silylene

Angewandte Chemie, EarlyView.
We demonstrate the sequential reactions between an imino(hypersilyl)silylene and aryl isocyanide or carbon monoxide as a molecular‐level model of the Fischer–Tropsch process, providing systematic and detailed insight into C–C bond formation during the homologation of C1 building blocks.

Rh‐Catalyzed Chemodivergent Parallel Kinetic Resolution and Desymmetrization of Enynes and Dienynes with Acrylamides

Angewandte Chemie, EarlyView.
Rh‐catalyzed chemodivergent parallel kinetic resolution of racemic 1,6‐enynes with α‐fluoroacrylamides or mixtures of different acrylamides proceeded via [2+2+2] cycloaddition and C–H alkylation to afford structurally and stereochemically distinct products with high selectivity under mild conditions.
