Abstract
AbstractAn efficient and general intermolecular Cobalt(II)‐catalyzed asymmetric alkylation of styrenes with (hetero)arenes including indoles, thiophene and electron rich arenes has been developed, providing straightforward access to enantioenriched alkyl(hetero)arenes with high enantioselectivity. Mechanistic studies suggest that the reaction underwent a CoH‐mediated hydrogen atom transfer (HAT) with alkenes, followed by a pivotal catalyst‐controlled SN2‐like pathway between in situ generated organocobalt(IV) species and aromatic nucleophiles. This is the first CoH‐catalyzed asymmetric hydrofunctionalization using carbon nucleophiles, providing a new strategy for asymmetric Friedel–Crafts type alkylation.
