Playing Reversi with H and N: A copper‐catalyzed intermolecularregioselectivehydroamination of styrenes with polymethylhydrosiloxane and hydroxylamine derivatives has been developed. The catalysis accommodates challenging β‐substituted substrates. Moreover, the chiral biphosphine‐ligated copper complex successfully forms benzylamines with good enantiomeric ratios.
A Ni-catalyzed enantioselective hydroamination of vinylarenes has been developed, affording a wide variety of α-branched chiral alkylamines in good yields with exclusive Markovnikov regioselectivity and excellent enantioselectivity. The SKP ligand was found to be crucial to both the reactivity enhancement and enantiocontrol of the reaction. The synthetic utility of the protocol was exemplified in a
